outlook web can't reach internet message

Microsoft currently reports Microsoft 365 service degradation that can prevent Outlook on the web from connecting and sending or receiving email, so check the Service Health page and wait for Microsoft to mark the incident resolved before changing account settings.^1^

What to do now

1. Open the Microsoft Service Health Status page linked above.
2. Look for an active incident affecting Outlook, Exchange Online, or connectivity to multiple Microsoft 365 services.
3. If an incident appears, no mailbox repair is needed. Retry Outlook periodically after Microsoft reports recovery.
4. Messages sent to you during the disruption may arrive after service resumes; if a sender receives a non-delivery report, ask them to resend afterward.

Microsoft directs Outlook.com users who cannot access the service to this status page.^2^

If the status page shows everything operational

Work through these checks in order:

1. Confirm whether the browser has internet access. Open another website. If that also fails, reconnect Wi-Fi or restart the router. If other sites work, the Outlook message does not necessarily mean your entire internet connection is down.
2. Check Outlook storage. Select Settings → General → Storage. If Microsoft cloud storage or the mailbox is full, Outlook.com cannot send or receive email. Mail sent to you while storage was full is returned to the sender and cannot be recovered; free space, then ask senders to resend it.^3^
3. Check the account state. If the password was recently changed, update it when prompted. Microsoft may also temporarily block an account after unusual sign-in activity.^3^
4. Isolate a browser problem. Open Outlook.com in a private/incognito window or another browser, then sign out and back in. If it works there, clear the original browser’s Outlook/Microsoft site data rather than changing mailbox settings.^4^
5. If mail connects but incoming messages remain missing, inspect Junk Email, the Other tab, forwarding, and inbox rules. Also select Filter → Sort → Date to restore chronological order.^3^

If none of these resolves it, in Outlook.com select Help, enter the problem, then scroll to Still need help? and select Yes to contact Outlook.com support.^3^
