Hello,

I had to reinstall Office 365 on my home PC and now Outlook is not recognizing my Outlook Data File found at C:UsersDellAppDataLocalMicrosoftOutlook.

The file type is shown as Outlook Data File.   Yet the file type ends in .com – (I thought it would be .ost)

I ran scanpst.exe and it repaired a few minor errors, still Outlook won’t recognize it.

The error message is “The file you chose is not an Outlook Data File.  You must select a new file of this type.

What should I try next please?

Thank you.

Randy
