Answer 1

Welcome to Microsoft Q&A!

Hello @Louisiana Underwriters, LLC I hope you are doing well,

What you are experiencing is currently linked to an active Microsoft 365 service incident tracked under ID EX1550543.

Microsoft initially reported intermittent connectivity issues affecting Exchange Online mailboxes in the Americas, and has since updated the advisory to confirm that the issue may impact general Microsoft 365 service connectivity across any region.

What this means for your environment:

Affected Services: Primarily Exchange Online / Outlook (desktop client, Outlook on the web, and mobile apps), along with potential authentication or connection timeouts across broader Microsoft 365 services (such as Teams, SharePoint/OneDrive, or the Microsoft 365 Admin Center) that rely on shared front-end connectivity infrastructure.

Action Required: No configuration changes are needed on your tenant or client devices. Microsoft engineering teams are actively working on mitigation.

How to track live status:

Open the Microsoft 365 Admin Center using a Global Admin or Service Support Admin account.

Navigate to Health > Service health.

Search for incident ID EX1550543 for real-time mitigation progress and root cause updates.(You can also follow official updates via @MSFT365Status on X).

Answer 2

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:

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.
Check Junk Email, Other, and Settings → Mail → Rules.
Check Settings → Mail → Forwarding for an unexpected forwarding address.
Remove any stuck message from Drafts or Outbox, then send a plain-text test without attachments.
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.
