    I was having the same exact issue with Outlook this morning after an update from Microsoft. Emails where not working. Then I noticed the date and time was wrong in the task bar. I fixed that then restarted Outlook and it sync'd right up with my email and starting getting them again. hope this helps.

    This worked (copying another reply)

    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.
