    So ANNOYING. Why can't Microsoft get it's own products working properly. I cannot add my MICROSOFT office 365 outlook account added to my MICROSOFT outlook app. Error codes are useless, support is non existent. I have deleted email accounts, outlook profiles, .tmp and .xml files, applications to no avail. The only thing that works is the charges on my credit card.

    Get it together!

    I had the same issue, but I managed to fix it.

    On Outlook application, go to File > Office Account, check whether your affected email address is signed in under Account (on the left side).

    If it is not, then try click Switch account and check whether your affected email address account is there.

    Most likely it is not, just add and sign in and it should be fixed.

    You can switch back to your original account after you added the affected email address account.
