Outlook Mail

Yes—there are signs of a broader Microsoft service disruption today, November 12, 2026, that may prevent Outlook.com users from sending, receiving, or accessing email.

Check the live incident and recovery status on Microsoft’s official service-health page before changing your account or reinstalling Outlook ^1^. Reports indicate that Outlook on the web and other Microsoft 365 connection methods may be affected, particularly in parts of North and Latin America ^2^.

If Microsoft shows the incident as active:

• Wait for the service status to show Resolved or Service restored.
• Messages already submitted may remain delayed; avoid repeatedly resending them.
• Test again afterward with a short, attachment-free message.

If service health shows no incident

Check Outlook.com directly in a private browser window. If sending or receiving still fails:

1. Open Settings → General → Storage. Full Microsoft cloud storage prevents both sending and receiving; incoming messages sent while storage is full are returned to the sender and cannot later be recovered.
2. Check Junk Email, Other, and Settings → Mail → Rules.
3. Check Settings → Mail → Forwarding for an unexpected forwarding address.
4. Remove any stuck message from Drafts or Outbox, then send a plain-text test without attachments.
5. Note the exact error or non-delivery report. Attachments larger than 25 MB cannot be sent through Outlook.com. Microsoft’s complete account-specific checklist covers these conditions ^3^.

If the problem continues after the service incident is resolved, select Help in Outlook.com, enter the issue, and then choose Still need help? → Yes to contact Outlook.com support.
