Thank you for reaching out to the Microsoft Q&A forum. I understand how frustrating it is when you stop receiving messages in Outlook.com.
In addition to what Q&A Assist suggest above, please try the following steps:
1. Check Outlook on the web
- Sign in to Outlook on the web in your browser
- Check all folders (Inbox, Junk Email, Deleted Items, Archive), ensure your inbox filter is set to All (not "Unread", "Flagged", etc.)
- Check Focused / Other tab (if Focused Inbox is enabled), emails may land in Other. You can also temporarily turn Focused Inbox off to test.
2. Check for hidden rules/forwarding
In Outlook on the web's settings, go to:
- Settings > Mail > Rules/ Sweep: delete any suspicious rules you did not create (especially rules that moves/deletes mail)
- Settings > Mail > Forwarding: make sure nothing is forwarding
3. Check mailbox storage
If your storage is full, Outlook won’t send or receive. Check storage (Settings > Account > Storage) and free up space if needed. You can see Mailbox storage limits in Outlook - Microsoft Support
4. Check your internet connection
- Make sure your device has a stable internet connection and try switching networks (e.g., from Wi-Fi to mobile hotspot) then test again.
- Check from a different browser/device or from an InPrivate/Incognito window,
(If needed, you can then clear the browser cache/cookies for Outlook.com.)
Could you please also confirm does this happen with all incoming emails, or just specific ones?
