You can easily execute tasks like reading or deleting the existing emails, saving draft, composing new emails, and more. And, you need not concern about the changes you make in offline; even though you work with Outlook while there is no connection with exchange server. Your OST file gets auto synchronize with the Exchange Server when the connectivity establishes. Also, your Exchange Server issues will not reflect in your OST file (Exchange Server does not affect the OST).

Yet, OST files are liable to corruption or damage and as a result, you will receive different error messages while working on it. And, there are various factors which affect your OST file, like faulty storage media where OST file is located, Exchange Server synchronization issue, etc. which leads to your OST file corruption.

The most probable reason for all issues you might face with OST file could be corruption. So now, the big question for which we need to find an answer is how to repair corrupt OST file.

Why I called it a BIG question?? Isn’t it a normal issue you face with the Outlook application? Of course not!

Although, Microsoft Outlook presented an inbuilt Inbox repair tool (scanpst.exe) to get rid of Outlook issues, running the same on a corrupt OST file directly is not suggested. But, why?

Here is Why You Shouldn’t Repair OST Files with Scanpst.Exe:

Let’s, look at the below report prepared based on the real-time experience of an Outlook user.

“I bump into issues with my OST file and hence, I scanned the file with scanpst.exe. The Inbox Repair tool found few issues in my OST file. But, it is not capable of fixing them. I still encounter the problems with my OST file, even after repairing it via ScanPST”.

Many Outlook users have come across above sorts of situations. And, this happens due to the fact that “leaving few IMAP configurations in Microsoft Outlook 2013 and 2016, rest of the OST files simply hold cached data of your Outlook”. So, Scanpst.exe works for some Outlook errors and it is not proposed to use with OST files. Hence, it is not suggested to run Scanpst.exe straightway to repair OST files.

Then, how to repair OST files? The answer is very simple! Just start with a fresh cache again, instead of trying to fix the OST file.

How to Solve OST File Issues?

To solve any (almost all) of the OST file issues, just rebuild the file instead of repairing it. And, here is how to rebuild OST files.

  1. Close Outlook and go to the location of your OST file.

You can find the location of your OST file by navigating to File > Data File Management > Data File > Open Folder in earlier versions of Outlook.

Or by following the path File > Account Settings > Account Settings… > Data Files > Open File Location in later versions of Outlook.

Also, you can find the OST file location based on your Windows operating system version. By default, OST file is located in,

C:\Users\%username%\AppData\Local\Microsoft\Outlook\ (in Vista, 7, 8 and 10 Windows editions)

C:\Documents and Settings\%username%\Local Settings\Application Data\Microsoft\Outlook\ (in Windows XP)

  1. After finding, simply rename your OST file (make sure your Outlook application is not running).
  2. Now, run the Outlook app and let it rebuild your OST file from the server.

This is the most dependable and easy method you can try to repair OST files.
