    Hello Experts,
    Came into work this morning and attempted to open my email (Outlook 2010). Got an error message that 'Outlook.pst is not an Oulook data file'. Following a suggestion, I deleted the profiles key in the registry. Upon opening Outlook it made me create a new account. I did so and it works fine, but all my prior email/contacts/calendar are in the other data file that won't open. I tried adding it to my list of data files but am still getting the error message. My new Outlook.pst file is under .../My Documents whereas my old file was under .../Local Settings/Application Data/Microsoft/Outlook. How can I get my data back?

    Hi dear

    It look like your PST file is corrupt somehow. Well do not panic you can repair your PST file easily.
    • Go for SCANPST.exe in Root folder inside Microsoft Office in your C:/Program Files/ folder
    • remember to take backup of your PST file before executing the SCANPST.exe command.
    It will repair your PST file , now if the issue remains then instead of opening your PST file in Outlook directly ,
    • Go To File
    • Open & Export option
    • click on Open Outlook Data file
    • it will open up the location where you Outlook data file is situated.
    • Open the the data file(.pst)
    Hope your issue will get resolved.
