Using Classic Outlook on Windows for personal email, calendar, and contact management
Hello Mack and Kathy Strouss,
I understand your frustration. Based on the timing and symptoms you described, this may have been related to the recent Microsoft outage that affected Outlook sign-in and connectivity for many users. During the incident, users could receive login-related errors even when their accounts were working correctly. [learn.microsoft.com]
Could you let us know if Outlook is working normally for you now? If the issue persists, please share any current error message and I'll be happy to help investigate further.
