  • Hi,

    Did this issue happen the first time you tried to start Outlook after you installed Office 2016?

    Which type of email account are you using? Exchange, POP3 or IMAP?

    Can you start Outlook in safe mode? To do this, press Windows key + R to open Run command, type outlook /safe and press Enter.

    >>Where do I repair it and where did ".pst" come from that is on the end of email address?

    To repair your PST file, you need to use the Inbox Repair Tool (Scanpst.exe). For your convenience:

    Besides, we may also try creating a new Outlook mail profile and then set up your email account in the new mail profile to see whether this issue continuous. To do this, please follow the instructions in this article:

    Hope this helps.

  • Finding root cause for this issue, is not easy, could be several reasons, like incorrect profile configuration. OST/PST data file corruption issues, which was not synched. Or corruption in the Navigation Pane settings file- profile_name.xml (profile name is the name of Outlook profile).For now, I can say,  repair Navigation Pane Configuration file and see, if you are still facing trouble.
