Sending, receiving, and organizing email in Outlook.com
Microsoft is experiencing a widespread Outlook/Microsoft 365 connectivity incident, so an all-day Outlook.com timeout today is most likely service-side and does not require changing your account or reinstalling Outlook. Public reporting confirms Microsoft acknowledged connectivity failures affecting Outlook/Exchange Online and other Microsoft 365 services beginning November 12, with effects continuing into November 13, 2026.^1^
What to do now
- Check the Microsoft Service Health Status site. Microsoft’s Outlook.com support page directs users there when Outlook.com cannot be accessed.^2^
- If Outlook.com is listed as degraded or unavailable, wait for Microsoft to complete recovery and retry periodically. Browser, password, and device changes will not resolve an active server-side incident.
- If this is a work or school Microsoft 365 account, ask the Microsoft 365 administrator to check Microsoft 365 admin center → Health → Service health for tenant-specific incident details.
- Avoid repeatedly changing the password or removing the account from devices during the outage, since that can create additional sign-in or synchronization work after service returns.
Only if Microsoft reports normal service
Try Outlook.com in another browser with advertising and pop-up blockers disabled for the site. Microsoft documents that AdBlock and uBlock can cause messages to load slowly or time out; the supported workaround is to exclude Outlook.com from the blocker and refresh the page.^2^
If the status is normal but Outlook.com still times out across multiple browsers, devices, and networks, report it through Outlook.com support once the site becomes accessible. Include:
- The approximate start time and time zone
- Whether web, mobile, and desktop clients all fail
- The exact error message or screenshot
- Whether other Microsoft account pages remain accessible
No detailed public Microsoft root-cause analysis for today’s Outlook.com timeout has been confirmed yet.
