Of course, there’s always a chance that your PST is stored in some other, non-default location.

Rather than telling you where the default location is, let’s use Outlook itself to tell you the exact path of your PST file and then use Windows itself to do the same.

I’m using Outlook 2013, but the technique is similar for older versions.

STATUS: WORKAROUND Our engineering team is aware of this issue and working on a fix that should be available soon.

For the most recent information on this issue, go to Contact Groups are not searchable with Autocomplete.

PST files are actually fairly complex databases that contain your mail, your calendar, your contacts, and even more when you use Microsoft Office’s Outlook mail program.

(Not to be confused with Outlook.com, the online mail service from Microsoft, which is completely unrelated.) The default location has changed a time or two over the years.

Microsoft provides the utility “scanpst” to scan and repair PST files suspected to have issues.

PST stands for “Personal STore” – as in your personal mail storage.

The result is that on the left, any PST files found are displayed.

Hover the mouse over (or tap-and-hold) on a result for more details: And of course, those details include the file’s location.

A PST is just a file, so using Windows own built-in search for files with the extension is another approach to locating your PST.
