Investigating
We are currently investigating an issue affecting Outlook sign-in for a subset of users. Some users may experience repeated password prompts in the Outlook desktop client and be unable to access email. Other access methods, including mobile devices and Outlook on the web, may continue to function normally.
Our team is actively working to identify the cause and restore full functionality. Updates will be provided as more information becomes available.
