Several Microsoft 365 applications, including Outlook experienced massive outages Saturday afternoon (March 1st, 2025).
iPhone users were prompted to re-enter their password in an endless loop and the Outlook website infinitely redirected you when logging in.
Many of our clients using Microsoft 365 reported similar issues. The outage seems to be resolved now but lasted for an hour or two.
