Sending, receiving, and organizing email in Outlook.com
Microsoft is currently reporting an Outlook/Exchange Online service incident that can prevent sending and receiving email; Microsoft has not provided a confirmed restoration time, so track the incident on the official Microsoft service health status page.^1^
What to do now
- Open the service-health page and look for Outlook.com or Exchange Online.
- Check the incident’s latest update and status:
- Investigating: Microsoft is still identifying the problem.
- Restoring service: corrective action is being applied.
- Extended recovery: service is returning, but not yet for everyone.
- Service restored: Microsoft has confirmed recovery.^2^
- While an incident remains active, repeatedly changing passwords, reinstalling Outlook, or removing the account is unlikely to restore a Microsoft-side service failure. Use another communication method for urgent work and retry Outlook after the next status update.
- After Microsoft marks the incident resolved, send a short test message to yourself and confirm that it appears in both Sent Items and Inbox.
For a Microsoft 365 work or school mailbox, an administrator can see tenant-specific details at Microsoft 365 admin center → Health → Service health → Active issues Microsoft is working on. The incident page includes Microsoft’s updates and any available recovery information.^2^
If service is restored but your mailbox still fails
Check your Outlook.com storage first. If Microsoft cloud storage is full, Outlook.com cannot send or receive messages; mail sent to you while it was full is returned to the sender and cannot later be recovered automatically.^3^
If storage is not full:
- If you recently changed your password, update the saved password in Outlook.
- Check whether the Microsoft account has been temporarily blocked because of unusual sign-in activity.
- If incoming messages alone remain missing, inspect Other, Junk Email, forwarding settings, and inbox rules.
- In Outlook.com, select Help, describe the send/receive failure, and proceed to Still need help? → Yes if troubleshooting does not resolve it.^3^
