My hard drive recently started going bad but before it went out I was able to copy most of my files off of it. I had Office 2010 using an exchange server. I had backed up my emails into a local folder in Outlook so the exchange server wouldn't delete them after its retention policy. I looked at F:\Users\username\AppData\Local\Microsoft\Outlook but the only large file I see is an .ost file. From the MS/Office help page it says:

Outlook Data File (.ost) The .ost file is synchronized with the items on the server that runs Exchange. Because your data remains on the Exchange server, you can re-create this .ost file on your new computer without having to back up the .ost file.

. This doesn't seem like where my emails would be kept, but I don't see any other promising large Outlook files. Can they even be imported back into Office 2013?

  • Your looking for a .PST file. If you don't have that file your are out of luck

Your .PST could be hidden. It sounds like you've clearly gotten past some hidden file obstacles, but this thread indicates there may be another hurdle:

My Office 2010 kept it in the Users' root directory (F:\Users\username\) as Outlook_Local.pst :)

  • Awesome that you found it, but it would be helpful to future users if you could describe how you found the .pst file. Were you able to look up the path from Outlook? Jul 11, 2013 at 16:42
  • I got desperate and looked for any pst file in the Users directory! Sadly the Office help files are outdated and have the incorrect path

    Ah. I think you can create *.pst files anywhere. They seem to go to C:\Users\<user>\Documents\Outlook Files by default for me. Jul 18, 2013 at 14:32
