I have an old OST file that I have been trying to convert to a PST. The problem I am running into is that I need to know what version of Outlook created the OST file. I don't remember the version. Is there any way to figure this out?

Software/Hardware used:
scanpst, ost2pst, pstwalker

Thanks. We'll let you know when a new response is added.

Outlook saves your data files depends on the version of Outlook you’re running. By default, Outlook 2007 and 2010 store OST files in your AppData folder at the following location:

C:\users\username\AppData\Local\Microsoft\Outlook

Starting with Outlook 2013, the location of OST files moved to the Documents folder. Outlook 2013 and 2016 now store PST files at the following location:

C:\users\username\Documents\Outlook Files

You can use Import/Export option of Microsoft Outlook to convert OST to PST format.

    I believe that shows the Outlook version and not the version of Outlook which created the ost file (it could come from another PC entirely). I couldn't find any info with regards to the structure of the ost file itself. Likely there is some identification there in the header of the file. But...aren't there only two versions that matter: 2003+ and pre-2003? Can you just try both options one at a time with a copy of the file? Or, is it more specific than that?
