Microsoft outage: Incident reference: EX1550543

Is Outlook down?

 Yes. Microsoft is currently dealing with a significant Microsoft 365/Outlook service outage today, 12 November 2026.

Microsoft has confirmed problems accessing Exchange Online mailboxes through multiple connection methods. Although reports initially highlighted the Americas, Microsoft subsequently indicated that Microsoft 365 connectivity could affect users in any region, so this is broader than an isolated company or local Outlook issue.
