With a very high probability, Recovery Toolbox for Outlook can restore an array of data from .pst files to their original state before they were damaged. To test this statement, it is necessary to:

  1. Download, install, and run the DEMO version of Recovery Toolbox for Outlook.
  2. Select a damaged .pst file.
  3. Run the analysis of the damaged PST file.
  4. Review the contents of the .pst file on the preview page.
  5. Select a folder on the disk for exporting recovered letters, contacts, appointments, reminders, and other data.
  6. Choose a saving method like a .pst file
  7. Save recovered objects - saving up to 5 objects per folder is available in the DEMO version.

How to Fix Outlook

If you need to fix an Outlook file that is corrupted for any reason, then the full version of Recovery Toolbox for Outlook will allow you to do this in a few simple steps. Outlook PST file repair occurs by copying the corrected data from the damaged .pst file to a new PST file on disk. The tool doesn’t fix or modify the existing PST file. All recovered data transfers to a new PST file with preservation of the folder structure and properties of all objects.


  • Windows 98/Me/2000/XP/Vista/7/8/10/11 or Windows Server 2003/2008/2012/2016 and above
  • Microsoft Outlook 98, Microsoft Outlook 2000, Microsoft Outlook 2002, Microsoft Outlook 2003, Microsoft Outlook 2007, Microsoft Outlook 2010, Microsoft Outlook 2013, Microsoft Outlook 2016, Microsoft Outlook 2019, Microsoft Outlook 2021 (Microsoft 365) must be installed on the user’s computer at the time of conversion (excluding Outlook for Office 365, Outlook for iOS and Outlook for MacOS).

This product does not export contact groups.


Our engineers have analyzed the content of OST (source) and PST (destination) files. The analysis revealed the types of data that are not carried over to the PST file after OST file conversion:

  1. old versions of messages, contacts, files and other objects
  2. removed objects
  3. blocks of data from earlier versions of messages, contacts, files and other objects. It is impossible to use these blocks to fully recreate the original object, which is why they can be treated as junk.

In other words, when you remove or modify a message, contact, reminder or meeting, the object is only marked as removed, but is not removed physically and remains in the OST file. The new version of the object is written to a newly allocated space, but the old version remains in the OST file as well.

If Outlook is in active use, the size of the OST file can grow quite significantly, while the actual size of data in the file remains the same.

In order to optimize disk space consumption and remove old elements, you need to configure the AutoArchive feature in Microsoft Outlook.

Note: it is recommended to backtrack the changed options after the export of the recovered data in Microsoft Excel has been completed.
  • search for and reading of old versions of documents is used by attackers for stealing users’ confidential information;
  • search for and reading of deleted and old versions of documents is used by police authorities to collect compromising information (Forensic Mode);
  • Recovery Toolbox for Outlook enables the user to search for data deleted from an OST/PST file and save it to the disk.


When converting large OST files (4 GB and above), you will have to use a 64-bit computer system. All program components required for converting OST to PST must be 64-bit. These include:

  1. Microsoft Outlook 64-bit
  2. Microsoft Windows 64-bit
  3. Recovery Toolbox for Outlook versions 4.0 and above

This allows you to bypass the limitations on the RAM that can be used by each component and convert OST files of virtually any size.

Converting huge OST files to PST files

Once all necessary components have been installed, run Recovery Toolbox for Outlook and perform the following actions:

  1. choose the OST file you need to convert on the program's first screen
  2. choose Convert on next page of Conversion Wizard
  3. choose the emails, contacts, and other information you want to transfer from the OST to the PST file
  4. choose the option to save as a PST file
  5. type or select a folder to use to save the data on the disk

The process of reading the OST file and then exporting it to PST takes a significant amount of time. The time it takes to convert OST to PST depends on your computer's performance, particularly the speed of your disk subsystem.

Note: When you install Microsoft Office or Microsoft Outlook, the 32-bit version is installed by default. To install Microsoft Outlook 64-bit, read the following article: How to Install Microsoft Outlook 64-bit?


To recover a very large Microsoft Outlook PST file (more than 4 GB), you'll need to have Recovery Toolbox for Outlook installed on your computer, as well as the following:

  1. Microsoft Outlook 64-bit
  2. Microsoft Windows 64-bit

If this software is installed, Recovery Toolbox for Outlook won't be limited to the size of operating data that 32-bit systems have. The program will be able to completely restore and save the data in a new PST file when working with the 64-bit versions of Microsoft Outlook and Microsoft Windows. If Microsoft Outlook 32-bit is installed on the computer, Recovery Toolbox for Outlook will encounter a limitation due to the amount of RAM that can be used in the restoration of data.

If you have the installation disc or distribution kit, you can install Microsoft Outlook 64-bit along with the 32-bit version of Microsoft Outlook. You'll find instructions for the installation of Microsoft Outlook 64-bit here:

This error occurs:

  • when Microsoft Outlook tries to open several Personal Store Folders that use one PST file
  • or if the Personal Store Folder is registered in Microsoft Outlook, but the original PST file does not exist on the disk or if the path to it is incorrect

To solve the problem, you should:

  1. Close Recovery Toolbox for Outlook and Microsoft Outlook
  2. Restart the computer
  3. Start Microsoft Outlook. Ignore the message This Personal Folders file (pst) is already in use with this profile while restarting Microsoft Outlook.
  4. Close all PST files Personal Store Folders being used, except for the main Personal Store Folder in the left panel of Microsoft Outlook. To do it, you should right-click the Personal Store Folder item and select the Close Personal Store Folder item in the context menu.
  5. Close Microsoft Outlook
  6. Open Microsoft Outlook again. If the error message This Personal Folders file (pst) is already in use with this profile appears again, the path to the main Personal Store Folder is incorrect or the PST does not exist on the disk. To fix this error, you should:
    • Find the source PST files on the disk. The best way to do it is to use the Microsoft Windows search feature (click Start | Search | For Files and Folders...), select All files and folders (for Windows XP) and then search for *.pst files on the computer.
    • Set the correct path to the file and its name in the properties of the main Personal Store Folder (right-click the Personal Store Folder item and select the Properties item in the context menu).


Microsoft Outlook data files contain main objects ( messages, contacts, notes, reminders, attached files and others) and service objects that are not shown to the user. While writing the recovered data to the new .pst file, the program does not write some service objects because there is no need to do it.


You performed the recovery operation at another computer or where another version of Outlook is installed. Our software uses Outlook components to compile the structure of a new PST file(s). So the recovered PST file is compatible with the version of Outlook that is installed on the system where the PST file was recovered.


Cases differ. Our software requires that the damaged file is fully readable so if you can copy the file to a normal, not crashed hard drive, our software will probably help you. Please download our software and try it for free. If it can help in your case, you can purchase it to disable the trial limitations.


Every object saved by Outlook to a file is stored in several blocks of up to 512 bytes. When a message is deleted, these blocks are not deleted and remain in the file. However, when new emails are sent or received, these blocks may be overwritten. As a result, the deleted email can be recovered only partially, for example:

  • if there is a subject, the message body or attachments may be lost;
  • if the subject is lost but the body is there, the email will be restored without From and To fields;
  • if the message subject and body have been overwritten, the attachment will be saved as a standalone file;
  • and so forth.

Recovery Toolbox for Outlook does everything possible to recover deleted data. If an object's data blocks are overwritten by Outlook, the object will be recovered only partially.


Repairing mailboxes after the corruption of the Exchange Server database file.

If the Exchange Server database file gets damaged, the server will still have *.edb files with users' emails. There will also be .ost files on users' computers containing the personal data of each user.

OST files can be quickly and easily converted to PST files using Recovery Toolbox for Outlook.

You can try recovering .edb files using Recovery Toolbox for Exchange Server. This tool converts individual mailboxes to .pst files.

We recommend trying both recovery methods to recover as much data as possible.


This OST-to-PST converter is an easy-to-use tool that operates like a wizard. With it, you can convert an .ost file to the .pst file format in a few simple steps. No special know-how is needed in order to use the Recovery Toolbox for Outlook OST-to-PST converter.

Microsoft doesn't currently offer a special Outlook OST-to-PST converter. All OST2PST converters have been designed by ISVs. Recovery Toolbox for Outlook, however, has a demo mode that lets you convert five objects per folder.


Recovery Toolbox for Outlook can read *.ost files any versions of Microsoft Exchange Server, any version of Microsoft Outlook (32- or 64-bit, ANSI or UNICODE). Software can read and convert *.ost files with any size of file.


The size of the converted .pst file shows the actual size of information stored in the ost file. If you do not make archives and do not start Cleanup Tool regularly for the original Offline Storage Folders, then the .ost file size is only growing. As a result, only 5-10% of the file can be used for a real user's data.


For the use of OST-to-PST conversion on a computer running Microsoft Outlook, the .pst file version will be the same as that installed in Microsoft Outlook. If the computer has Microsoft Outlook 2007 or higher installed, the size of the resulting .pst file can exceed 2Gb. If you use MS Outlook 98-2003, the size of the resulting file will be limited to 2Gb. In this case, Recovery Toolbox for Outlook will create several .pst files in which to store all the data from the source .ost file.


Recovery Toolbox for Outlook exports messages, contacts, appointments and other data from *.ost files as MSG files. The software converts and saves all data from .ost files to the .msg file format. Later, the user can drag and drop or import the saved *.msg files in any of the popular client software programs, including Lotus Notes, Microsoft Live, The Bat, Eudora, Incredimail, Mozilla Thunderbird, etc.


Microsoft Outlook has no function with which to import data from *.ost files. To open an *.ost file in Outlook, the Exchange Server and Windows Domain Controller must be working and available for user authentication in both of the respective services. Only after that is it possible to transfer the contents of an .ost file that is open in Outlook to a .pst file that is also open in Outlook.

If the Exchange Server or Windows Domain Controller isn't accessible or doesn't work, or if the user can't be authenticated, access to the data will be denied and Outlook won't open the .ost file.


The original .ost file must be converted to a pst file using Recovery Toolbox for Outlook and then opened in Outlook. Conversion from OST to PST using Recovery Toolbox for Outlook doesn't require the availability of Exchange Server or Windows Domain Controller.


To correct the following issue 8004010F when using POP3/SMTP accounts in Microsoft Outlook, do the following:

  1. Download, install and start Recovery Toolbox for Outlook from the site:
  2. Choose a corrupt .PST file in the first window
  3. Choose Recovery Mode
  4. Choose a folder to save a recovered file
  5. Replace the corrupt PST file by a recovered one

Last, you should replace the damaged file to a recovered one or merely add the recovered file to the list of data files in Outlook.

  1. Start Recovery Toolbox for Outlook.
  2. Choose the needed file of PST format.
  3. Choose Rcovery mode.
  4. Start the analysis of the damaged file and wait until it is finished.
  5. Preview the contents of the repaired file.
  6. Choose a folder to save the repaired file.
  7. Choose Save as PST file.
  8. Click the Save button.

After a successful repair, you should properly connect a file of PST format to Outlook 2019:

  1. Open Outlook 2019 and choose File | Info.
  2. Click Account settings.
  3. Choose Account settings in the popup menu.
  4. Choose the following tab Data files.
  5. Choose a data file from the list below.
  6. Click Delete if the file is present.
  7. Click Add and provide the correct PST file path.
  8. Open Microsoft Outlook, try to send and receive your email.


If you’d like to update to Microsoft Outlook 2019 and you have already an older version of Outlook, for example, 2016/2013/2010/2007, and the like, I would advise the following:

  1. Make a backup copy of Outlook data files (files of .pst and/or .ost format)
  2. Remove Microsoft Office completely
  3. Make a new clean install of Microsoft Outlook to another folder. For this purpose, use the option of advanced installation and enter the installation path.
  4. Open the list of Outlook data files and add a previously saved PST file of the previous application version.

Please select a damaged Microsoft Outlook *.pst file:

I tried to install Outlook 2021, bought from the MS site. Unfortunately it was unsuccessful. Stating that my existing outlook (2010) data file is corrupt. Your software fixing the data file.

John 02-26-2023

I had a large ost file of about 20GB on an imap account that no longer existed. I needed the data converted to pst format. Tried various exports of the data using Outlook but they all failed. The recovery tool converted the entire file to a pst with no loss of data. Exactly what I needed.

mfitzgerald 02-19-2023

Advantages: 1. fast program. 2. Reads everything. Good preview. Disadvantages: 1. Needs Outlook not version 365 2. Needs Windows

Maureen G 02-02-2023

My source files were not damaged. Due to issues with outlook, I had to remove my outlook email address and re-add it. Before deleting the email address I copied the .ost file. I used the recovery software to convert the copied .ost file to a .pst file and added the .pst file as a datafile in outlook.

Vincent Liou 12-15-2022

They weren't damaged. Rackspace had a severe Exchange outage (Google it!) and so we are trying to convert from OST to PST so we can move to O365.

Hubert 12-14-2022

The original OST file was not affected. I wanted to recover an old email account that could only be found in the ost file. And so it had to be converted to a PST file and opened in Outlook.

Greg 12-07-2022

The Exchange service we were using stopped functioning. When switching to a new service I didn't convert my .ost to a .pst. Which I subsequently did with Recovery Toolbox, excellent tool. I learned a lot about cache files.... like the ost doesn't contain mail older than a year by default. Which I can see in your logger before doing the conversion. So I'm still missing 18 months of mail and hoping I will eventually get it back from the Exchange service. Now having trouble re-integrating the autofill file.dat in the Cache folder as I see that's separate. Greg

Carolina Julian 11-22-2022

Everything recovered as if it were magic! It's good to have something that solves like this

Susan Clark 10-08-2022

I hired a tech from my local Wired office who tells me that the files were probably damaged during a M/S update. He says he "has never seen this problem before", uninstalled the entire Office suite after trying all other options and the problem persisted. Since I ceded control of my computer to him, I am not sure how he proceeded from there but he did eventually fix it. Thankfully, his costs are reasonable.

Rick 08-30-2022

One Outlook PST file repeatedly asked for password but didn't accept the password that I typed. I hadn't forgotten the pw and I absolutely know that I was typing it correctly. I tried the MS pst repair tool and some other free tools and then some that do a "teaser" recovery of a few items per folder. This tool recovered the content of the pst. The downside is that it didn't actually recreate the pst, it just recovered the content. The folders were recovered but not the folder structure, nor were the calendar entries recovered correctly particularly those with recurrences. To be honest, I am just grateful to have all the data back available to me and there appears to be nothing missing. Thank you for an excellent 99% product.

Carl Barringer 07-26-2022

I reformatted my computer. The .PST did not get backed up in my incremental backup since Microsoft does not change the modified date of it unless you disconnect from Outlook. I used the recovery tool to get a .OST from the backup and convert it to a .PST - just what I needed!

Rodrigo 06-26-2022

Value software to convert ost to pst.

JIMENEZFDJ 06-09-2022

Hi, I lost SENT ITEMS folder from my Outlook 2016 Inbox, it appears that I did something wrong with my mobile Outlook Client (Android) that made this happen, so synchronization ocurred with my Godaddy e-mail hosting and SENT ITEMS were fully deleted from my Outlook Laptop Client. I tried to recover these emails from my Laptop computer, but recovery was only partial, some of them were successfully recovered, others not... I recovered only about 20% of the emails. Thanks...!!!

Gerardo Ramirez 06-09-2022

We decided to license Recovery Toolbox software for converting .OST to .PST files from some officers who have retired from Microsoft 365 licensing. Additionally, it allowed us to recover PST files that could not be opened and used from Outlook. Very good tool!!

kiran 05-22-2022

Taking to long for PST conversion. Still Pending. More than 12 hrs.

David Kenyon 04-26-2022

No recovery needed, just converting an old Hosted Exchange domain mailbox from OST to PST to move into the customers new domain O365 setup. Worked perfectly and was really fast. Took about 30 mins for a 15GB OST file to convert to PST.

Noize 01-10-2022

fast and convenient service for converting Outlook mail

Ty160 12-13-2021

Easy to convert 5.6Gb Exchange Server .OST file. Thanks!

Tiana Acosta 04-27-2021

I was allowed to take a corporate large pst file and fix it at home on my pc. I thought it would take 2 days since the file size is 48 GB !! But the program fixed the inaccessible file in less than 3 hours.

Makaila Hughes 04-13-2021

I tried to fix errors in the file by use SСANPST.exe, but it didn't help. Recovery Toolbox for Outlook was able to get letters and contacts from the pst file.

Santiago Marks 04-04-2021

Thanks for helping to repair corrupted Outlook 2003 .pst file.

Jamie Carroll 03-22-2021

Fine. I was able to wait for the complete synchronization of the .OST file, and then converted it to .PST. The file size came out approximately 34GB. Everything went fine, I was able to retrieve all my letters.

Lynn Phillips 03-16-2021

Thank you.

Cingulum Yutah 02-08-2021

God, what a program! Converted .ost to .pst, and also got offline access to the account. Super!

Joe Beam, PhD 02-08-2021

I haven't used Outlook for several years. There was an attachment to an old Outlook email that I needed to find and retrieve. That's what I used your software for.

Trace Oakley 01-20-2021

I cant open the .pst file even after repairing, Outlook said "outlook.pst is not an Outlook data file". If you have the same problem, write to the support, they sent me step-by-step instructions, after which everything started and everything works

Thymiaterion 01-13-2021

I downloaded the program, installed and repaired the .pst file. But without an Outlook client, the fixed file won't opening. I will supplement the review when I look at the contents of the file at work.

Zakai Xzavier 12-28-2020

After system restore (Windows 7), I had to deal with troubleshooting the missing Outlook messages. I had a .PST file, but the fallback system caused emails to be deleted. It took less than a minute to fix the .pst file (online), the service recovered the deleted messages.

Luka Luca 12-22-2020

My address book became complete again, I fixed the damaged file and got my contacts and letters back.

Mary Arjun 12-15-2020

The goal is to restoring MS Outlook contact history, and as a result, both contacts and deleted messages were undeleted. Twice happy!

Ostensory 12-07-2020

The program repaired all information about my tasks from a corrupted Outlook 2007 .pst file. Now I can export all data to Outlook 2019.

Gus Griffin 08-11-2020

I bought Recovery Toolbox for Outlook to recover mail, but I cannot find the .pst file. I called support, they told me to download their free utility "Mail Undelete Recovery Toolbox Free", which eventually helped me restore the folder with lost letters and contacts. I am very grateful for the help, they said that the money will be returned within 10 days. thks

Damn such a stupid mistake, while restoring, I somehow unchecked the "Outbox" letters. As a result, in Outlook, I saw only the contents of the Inbox messages. Only after a second "thorough" recovery, I was able to recover all the contents of the mail correctly. P.S if you see the letter, please excuse the angry statement)

Santino Dwayne 08-01-2020

I don't know why there is a converter here, because Outlook already stores all letters in .PST. I selected letters from the email, pressed the "recover" button and received all the letters. The program is definitely needed, while I used it once.

Damn guys, you are super!! I no longer hoped to find a program for repairing Outlook emails, especially for Vista operating system. The accountant asked to try your product and it worked!! We were able to export all emails from corrupted .PST file and open them in Outlook 2007 Today, I'll ask Boss to write a check for the new Windows 10 operating system! Guys, you know your business!

I usually use the native Microsoft Outlook utility (Scanpst.exe) to fix errors, but today I first encountered such a problem, the utility crashed. Work colleagues have recommended your program. The program really helped repair contacts and emails from a damaged .pst Outlook file, but for me it is a little more complicated than the native tool

I think I have gotten it recovered. I uninstalled outlook 2010 32 bit and installed outlook 2010 64 bit. I was going to then run the recoverytoolbox program but when I clicked on my newly installed outlook it found my data file. I am still confused as to what happened but I am back to work. Thanks, Dennis

John 07-26-2018

Plus: I've converted 11Gb OST file. Minus: Price is expencive $50. And I've wait 7 hours.

Plus: 1) Can try before you buy, make sure anti-virus is happy, that it finds and fixes corrupted files. It will then fix 5 files per folder for free or pay for the rest. So you can make sure it will work for you before paying. 2) Can work with Outlook x64 Minus: Not free.

My .pst files were restored, that's all I needed. Tool deserved to be used, at least one time, to see it in action...

TONYPONS 01-07-2014

Tool restored my dozen corrupted emails after unexpected switch off my computer. Design might be a little better One of best tools I've ever used for damaged .pst files

NIKFRANCIS 12-11-2013

I've lost many outlook messages this morning. Tool restored them about some hours ago. Effective tool for MS outlook 2010.


Tool forced me to forget about lost .pst files of Microsoft Outlook 2003. I chose it and was lucky.

Tim Rosanos 07-21-2013

Tool makes own business very well. Sometimes tool suspend my computer for a little time. I bought it, and it's one of the best products which I have been ever seen.

PETER WESKINS 03-01-2013

Software handled my trouble with crashed Outlook 2007 emails after turning my computer off. I acquired this tool for some minutes, during the same time it solved my issue.

Donny West 11-11-2012

Software for some minutes found out crashed MS Outlook emails and got me back data. Tool needs a lot of resources of hardware for its working. In result, most of corrupted emails were restored, I'm almost glad, almost.

MASON RODGERS 02-07-2012

My Outlook 2003 emails were fully restored. High requirements of product, especially under working with huge email messages. My machine is on a ledge of cancel. Positive solution, but not for old computers.

Plus: Easy to use. Relatively inexpensive. Completely restored an intact OST file. Minus: None for me. I don't know whether it works on a corrupted file. SUMMARY: I lost an MS Small Business Server (2008) in a storm. Most of the users were using cached Exchange mode in Outlook, and I was able to open Outlook and copy their existing folders to a PST file. I forgot a couple of folders on one PC (Outlook 2007), though, and I lost access to the OST file after joining the PC to the rebuilt domain. I downloaded the demo copy of Recovery Toolbox for Outlook onto my laptop and used it to examine the OST file. It successfully recovered five items from each folder in the file, so I purchased a licence. Got the email with my license key within about five minutes, applied it to the program and recovered the entire OST file a couple of minutes later. No problems, and the user was happy! I have not tried this on a corrupted OST or PST file, so I can't speak to how well it works on those. But on an intact OST file that you cannot open in Outlook, it worked like a charm. Plus, it cost a lot less than some other recovery programs.

PLUS: The software was able to recover an .ost file that was created using Outlook 2010 and Outlook Connector_v14.1. The scanned happend quick for a file under 500MB. The price of the software is well worth it to recover a .ost file!! Offer: I haven't come across any problems with this program, I only just used it like an hour ago. This con is more towards MS and Outlook 2010, if you create a program that uses a file (.ost) that program should be able to open it and be used like before. Total: If you use MS Outlook 2003, 2007, 2010 this program will help you recover .pst and .ost files! The price is great and to this work the first time out. Even thought some of the data was missing, but I think that is more because of MS Outlook .ost file (local file) did not have saved in it. If you need to get calendars, contacts (root level), deleted items, drafts, Inbox (email), Journal (only if the .ost has it in it), Junk Email, and Sent Items then this program is for you! If your using Outlook 2007, 2010 and the plug-in "Outlook Connector" there are 3 folders that this program MIGHT not be able to recover. Any folder in Outlook with the following after the folder name: This is because you have an Hotmail/Windows Live email account and your are using Outlook's plug-in "Outlook Connector". It just goes to show you MS Office Outlook 2010 is still lacking in basic software usability to import a .ost file. Thanks Microsoft way to drop the ball yet again.

Price is very reasonable compared to other programs written to do the same thing. Works to extract data from pst files and also ost files. Many of the other programs will only do pst files. Scanner is slow. Even on a fast computer it can take 1 hour to read the contents of a 2 Gb size file. And then take 3-4 hours to write the contents to a new pst file. I have used the program for 3 years. I needed an ost recovery program and a review of internet indicated that most of the progrmas that would do this started at $300 for a 1 time use. Over the 3 years that I used this program it has paid for itself many times over. If I need to fix someones file I will take the file to my home shop and run the program on a quad core system over night. Recently I was unable to recover a file with this program and so I purchased a more expensive program. The new program ran faster and worked better. However,the new program would only repair pst files, it would not read ost files. So I now use both programs. This program to recover ost files and the other one to recover pst files. For anyone needing to repair pst or ost files this is the place to start. Most of the other programs available that have been written are much more expensive.
