There appears to be a widespread Outlook/Outlook.com access disruption today, November 12, 2026; check Microsoft’s live Service Health Status page for the latest recovery update rather than changing your account settings.^1^
Check current progress
- Open the Microsoft Service Health Status page.
- Look for Outlook.com or Microsoft 365/Exchange Online, depending on whether this is a personal or work/school account.
- If the status is not green, no local repair is required. Wait until Microsoft marks the incident Service restored, then try Outlook again. Microsoft’s Outlook.com support guidance specifically directs users with access problems to this status page.^2^
For a work or school account, an administrator can also open Microsoft 365 admin center → Health → Service health, select the active incident, and review its latest update, user impact, and restoration status.^3^
The available reports confirm a broad problem today, but they do not provide a verified restoration time or confirm that every affected mailbox failed at exactly 9:00 AM Pacific.^1^
If Service Health is green
If Microsoft reports the service as healthy but the mailbox still cannot be opened:
- For a personal Outlook.com/Hotmail account, run the Microsoft account sign-in troubleshooter. Microsoft distinguishes account sign-in failures from Outlook.com service failures.^4^
- For a work or school account, ask the Microsoft 365 administrator to select Report an issue on the Service health page if no matching incident appears.^3^
