Microsoft says outage affecting Microsoft 365, Outlook, other services has been resolved

Summary:

A major Microsoft outage temporarily disrupted access to Microsoft 365, Outlook, Teams, and Azure services globally. While resolved within hours, users experienced email delays, failed logins, and file sync failures. Such outages are commonly triggered by faulty server updates, DNS misconfigurations, or traffic spikes during peak hours. Microsoft confirmed this incident originated from an Azure Active Directory authentication error during routine maintenance.

What This Means for You:

• Impact: Temporary inability to send emails, join Teams meetings, or access SharePoint files
• Fix: Fully restart Outlook/Teams and refresh browser sessions
• Security: Verify sender authenticity – phishing attacks surge during outages
• Warning: Don’t delete local files – syncing will resume post-recovery

Solutions:

Solution 1: Hard Refresh Services

Outlook may show cached error messages even after Microsoft fixes the issue. Close all Office apps completely via Task Manager (Windows) or Activity Monitor (Mac). Delete temporary files with these commands:

Windows: del /f /s /q %localappdata%\Microsoft\Office\16.0\Wef\*
macOS: rm -rf ~/Library/Group\ Containers/UBF8T346G9.Office/

Relaunch apps to force fresh authentication.

Solution 2: Check Service Status

Always verify ongoing issues via Microsoft’s official status portals. Use these resources:

Office Status: status.office.com
Azure Status: status.azure.com

Bookmark these pages and enable incident SMS alerts. Third-party sites like Downdetector can falsely report outages.

Solution 3: Fallback Authentication

If corporate logins fail, use Microsoft’s temporary web access:

Outlook Web: outlook.office365.com
Teams Web: teams.microsoft.com

Enable offline mode in desktop apps beforehand via File > Work Offline to draft emails during disruptions.

Solution 4: Reset Network Stack

Local DNS caching may prolong outage effects. Flush your connection with:

Windows: ipconfig /flushdns && netsh winsock reset
macOS: sudo killall -HUP mDNSResponder
Linux: sudo systemd-resolve --flush-caches

Restart routers and disable VPNs until services stabilize.
