Hi Shekhar Raj
Thank you for reaching out to the Microsoft Q&A Forum. I understand how concerning this is, being able to send but not receive new emails can interrupt important messages.
Have you already tried the steps mentioned in the Q&A Assist reply under your post? If yes, did you face any difficulties with those steps?
Could you please also confirm does this happen with all incoming emails, or just specific ones?
In the meantime, please try the following steps:
1. Double-check Outlook on the web
- Sign in to Outlook on the web in your browser
- Try to send a test email to yourself from another email account (or ask someone to send one) then check if the emails appear there.
- 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 any hidden rules/forwarding
Still 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.

If the steps above don't work, please feel free to let me know how it goes so I’ll help you further. Thank you for your understanding and patience.
