Stellar Outlook PST Repair 3.0

Few things are more troubling than to start your day by loading up Microsoft Outlook, only to have it complain that "outlook.pst is not a personal folders file".  You're sitting there with your first cup of coffee wondering: what the heck does that mean?  If outlook.pst is not a personal folders file, then what is it?  And what should it be?

The short answer is that outlook.pst is the file that Outlook normally uses to store all of your data, such as email messages, contact records, calendar events, notes, etc.  Anything that you save in Outlook ends up getting stored in a single pst file, also known as a personal folders file.  And typically that works fine.  But if the file ever gets corrupted or damaged in any way, then Outlook may no longer recognize it as a valid file and you'll see the error message that began this article.  So this error is simply a cryptic way that Microsoft is telling you that there is a problem with the file and Outlook will no longer be able to use it unless it gets fixed.

Outlook files can get corrupted for any number of reasons.  Your computer may have lost power or not been shut down properly.  An upgrade of Outlook may not have completed 100% correctly.  Another application might have a bug or memory issue that damaged the pst file.  Or you may have been moving files from one machine to another, or from one medium to another (such as to backup disks or CDs).  No matter the reason, Outlook is rather particular about this file and will not operate if it detects a problem.

Fortunately data corruption isn't that common of an occurrence, so most people will never see this error message.  But if you are one of the unlucky ones, you'll be wondering what to do about it.  The first step is to see if you have a recent backup of the file that isn't corrupt.  If you don't, the next step is to try running Scanpst.exe, a free repair utility provided by Microsoft.  And if that fails, or is unable to open the file, you should try a free download of our Stellar Outlook PST Repair, to see if it can restore the file and recover all your data.
