My Microsoft 365 is down so what do I do

There are current signs of a broader Microsoft 365 disruption, so avoid reinstalling Office or changing account and billing settings until Microsoft reports that the incident is resolved.

What to do now

1. Check Microsoft’s Service Health Status site.
   It provides information about known Microsoft 365 issues when users cannot access the admin center. Microsoft posts investigation, mitigation, and recovery updates for active incidents ^1^.
2. Wait for the service to recover and retry periodically.
   Public user reports currently indicate Microsoft 365 problems, particularly involving Exchange ^2^. Teams also has elevated problem reports ^3^. These reports indicate broader impact, but Microsoft’s Service Health Status site remains the authoritative source for recovery updates.
3. Use temporary alternatives where available.
   • If the desktop application fails, try its web version.
   • If Outlook is unavailable, avoid repeatedly sending the same message; queued or delayed messages could be delivered after recovery.
   • Save work locally until OneDrive synchronization resumes.

If you administer a business tenant

Sign in to the Microsoft 365 admin center, then select Health → Service health. Open the active incident to see its affected services, user impact, latest update, and recovery status. Service Support admins and Helpdesk admins can also view this page ^1^.

If it still fails after the outage is resolved

Restart the affected application or refresh the browser once, then test again. If only your account remains affected:

• For Microsoft 365 Home or Personal, use Contact Microsoft at the bottom of Microsoft’s recent Office issues page ^4^.
• If an Office application specifically displays a subscription or payment warning, check the subscription separately. That is a different issue from a service outage; Microsoft documents that payment problems can cause an expired or suspended subscription ^5^.

Do not deactivate or reinstall Office while the status page shows an active incident; those actions will not repair a Microsoft-side service disruption.
