Microsoft has not published a dependable full-restoration time for the current Outlook/Microsoft 365 outage; monitor the official service-health dashboard for the next update and tenant-specific recovery details. ^1^
Check the latest update
- Without administrator access: Open the public Microsoft service-health page.
- Microsoft 365 administrator: Sign in to the Microsoft 365 admin center, then select Health → Service health → Active issues Microsoft is working on. Open the Exchange Online or Outlook incident to see its current status, mitigation progress, next-update time, and any estimate applicable to your organization. ^2^
- If the admin center is unavailable, continue using the public status page.
Some recovery may occur gradually, so Outlook could begin working for certain users before the incident is marked fully resolved. Avoid reinstalling Outlook or recreating profiles while Microsoft lists an active service incident; those actions will not resolve a Microsoft-side outage.
If Microsoft marks the incident resolved but Outlook still fails, test Outlook on the web and another device. A problem limited to one device can then be handled as a client-specific issue.
