no connectivity

A current Microsoft/Outlook disruption is affecting access to some personal Outlook.com mailboxes, so monitor Microsoft’s service-health page for recovery rather than changing your account or device settings.^1^

What to do now

1. Open the Microsoft service health status page.
2. Expand Microsoft consumer products, then check Outlook.com.
3. If Outlook.com shows an active incident or service degradation, wait until Microsoft marks it resolved and then try signing in again. Microsoft Support directs Outlook.com access problems to this status page.^2^
4. Avoid repeatedly changing your password, removing the account, or reinstalling Outlook while the incident remains active; those actions cannot repair a service-side outage.

Microsoft has not provided information here that guarantees full restoration by tomorrow. The service-health page is the authoritative place for the latest recovery status and update time.

If service health shows recovery but access still fails

• Try Outlook.com in a browser.
• If you cannot sign in, use the Microsoft account sign-in helper referenced by Microsoft Support.
• If you can sign in but cannot send or receive messages, check whether your Microsoft cloud storage or mailbox is full. Full storage prevents sending and receiving, and messages received while storage is full may be returned to their senders.^3^
• If the problem continues after Microsoft reports normal service, use the interactive troubleshooter on that same support page.
