Outlook outage prompts iPhone reauthentication after global sign-in disruption
A worldwide Outlook.com sign-in outage left some users signed out or seeing 'too many requests' errors; Microsoft says iPhone users must manually re-enter their credentials in the Mail app to regain access. Service health returned to normal by around 7 PM UTC, but the root cause and regional impact were not disclosed. The incident follows other recent Exchange Online/microsoft 365 sign-in outages across Microsoft services.
