    My Outlook application is hanging up while loading my profile. Is there a way to fix it

    • Molly Owen says:

      Hello Brook,
      Thanks for reaching us.
      Outlook application can lag or freeze when it is not frequently updated.
      This is a minor issue and can be easily fixed by uninstalling and reinstalling the Outlook application. Lastly login with appropriate profile credentials. However, before uninstalling the Outlook application it is recommended to take a backup of the PST file.

      A PST file is Outlook data file. Outlook locally stores all the Outlook components such as emails, contacts, schedules in a PST file. FYI, the default .pst file location is “C:\Users\Documents\Outlook Files”

    Hello Molly. I tried to import my PST file from another computer. So I replaced my existing PST file with an old file but when I opened my Outlook it is not loading data from imported PST file. Is my PST file damaged or did I make any mistake while importing?

    • Molly Owen says:

      Hello Cassie, I hope you are having a great day. I have seen your comment. Can you please mention the location of the pst file and how you replaced it.

      • Cassie says:

        Location of the pst file is in documents and the folder name is Outlook files. So after logging into my outlook account deleted the existing pst file and replaced it with my old file. I closed my Outlook when I replaced the pst file and when I reopened Outlook I expected it to load all my emails from the old pst file. But, it didn’t happen.

        • Molly Owen says:
