New Outlook for Windows Error 401

Is anyone else running the “new” Outlook for Windows and experiencing problems with the latest update? I restarted the app this morning following an update and when it opens I get a screen with the following error: “Something went wrong – We ran into an error – Error: 401”

I tried the provided troubleshooting button (could not find problems), reset the app, and reinstalled without success.

I’m just wondering if it is me or if a broad issue is going on.
