We are experiencing Outlook App authentication fails across our organization suddenly.
No changes have been made on our end.
Is Microsoft having issues or is anybody else dealing with this

It may be too late for my reply, btw, what kind of authentication are you using? (e.g. Exchange Active Sync)
How about OWA (Outlook Web App), working?
