Update: Microsoft says that the service outage has been resolved. And until Microsoft can fix the problem, you’ll be locked out. Logging out, though risks dropping access, as Microsoft will force you to reauthenticate. The bottom line, then, is that if you’re logged into a Microsoft service, such as the mobile version of Outlook, or of Teams, stay logged in, and you’ll keep getting your email and messages from your co-workers. “Affected users are encouraged to keep existing sessions going and to avoid re-authenticating to services.” “ Existing sessions do not appear to be affected,” the company wrote. Microsoft, however, has some advice on what to do, and what not to do. “We’re evaluating additional options to remediate the problem.”
“Rolling back the previously described change did not resolve the incident as expected,” Microsoft said on its status page, under the “more details” heading.
