No authoritative restoration time has been published for today’s Outlook/Exchange Online outage, so monitor Microsoft’s official Service Health channel for the recovery notice rather than changing or reinstalling Outlook.
Reports confirm a significant Microsoft 365 email disruption in the Americas on November 12, 2026, affecting Outlook/Exchange Online access and related services for some customers.^1^ No reliable public source currently gives a firm completion time.
Check the current status
- Personal Outlook.com/Hotmail/Live account: Open Microsoft’s Service Health Status site. Microsoft directs Outlook.com users there for access problems.^2^
- Microsoft 365 work or school account: Ask your administrator to open:
- Microsoft 365 admin center
- Health → Service health
- Select the active Exchange Online incident to see Microsoft’s latest update, affected features, and next-update time.
The dashboard’s Active issues Microsoft is working on section lists current incidents; Issue history records resolved incidents from the previous 7 or 30 days.^3^
If the admin center cannot be opened, use the unauthenticated Service Health Status page referenced in Microsoft’s service-health documentation.^3^
If your account remains down after Microsoft reports recovery
- Business account: Your administrator should create a support request from the Microsoft 365 admin center if your tenant is not covered by the listed incident or remains affected after resolution.^4^
- Personal Outlook.com account: In Outlook.com, select Help, enter the problem, then scroll to Still need help? → Yes to contact support.^2^
This Microsoft Q&A forum cannot restore the service or provide an unpublished deadline. Mail access should return as Microsoft completes recovery; delayed messages may take additional time to process afterward.
