2] Repair corrupt Outlook PST files using Fix It

While the Inbox Repair Tools is quite easy to use, if you are too lazy even to do this, you can download and run Microsoft Fix It 50569 from KB272227. This Fix-It will do the needful automatically.

A PST file has a 2-GB size limit. Once this limit is reached, corruption will start occurring.

In such a case if the Inbox Repair Tool cannot fix the corruption, you can try to use the Oversized PST And OST Crop Utility or the PST2GB Tool from Microsoft first, and then again repeat the Inbox Repair Tool.

This tool deletes 25 MB of data from the file to bring the file back within the allowed. While this tool was used in the earlier versions of Outlook, I am not sure about its use or applicability in the current Outlook version. So please read all the instructions and exercise utmost caution should you think you can and should run this tool. If you need more help with this, you may contact Microsoft Support.

TIP: These software will help you recover forgotten Outlook PST Password.
