No service for 10 hours

Microsoft is currently reporting a service degradation affecting Microsoft 365 and consumer services, so email failing simultaneously on the laptop, iPad, and iPhone is most consistent with that outage rather than a problem with each device.^1^

What to do now

1. Check the Microsoft service health status for updates and recovery progress.^1^
2. Wait until Microsoft marks the incident resolved. Access should return automatically; repeatedly changing passwords, deleting accounts, or reinstalling Outlook is unlikely to help during a service outage.
3. After recovery is reported, try Outlook.com in a browser first. Microsoft specifically directs Outlook.com users with access problems to the Service Health Status site.^2^
4. If browser email works but the iPhone or iPad still does not sync, then troubleshoot the mobile app. Microsoft notes that when email works on the computer and there is no outage, the problem may be isolated to the mail app.^3^

If service health shows recovery but email still fails in the browser and on every device, contact Microsoft Support for the Outlook.com account. For a work or school account, contact the organization’s Microsoft 365 administrator.
