Hello andy white,
Thank you for reaching out to Microsoft Q&A Forum. I understand how frustrating it is when your Hotmail can’t send or receive emails even after going through multiple troubleshooting steps.
Before we proceed, could you tell me whether you’ve already tried the steps suggested in the Q&A Assist reply above? If yes, which ones and what happened?
Since you’re able to sign in but the issue continues, here're a few additional checks that you could try:
1. Test on Outlook on the web
Please sign in at https://outlook.live.com and try sending and receiving an email there.
- If it fails on the web, this points to an account-level restriction.
- If it works on the web but not in the app, the issue is local to the app/device.
2. Review Junk Email and Safe Senders settings
In Outlook on the web, go to Settings > Mail > Junk email and confirm:
- No important addresses or domains are blocked under Blocked senders and domains
- Add trusted addresses to Safe senders and domains and test again
3. Check mailbox/storage quota
If your storage is full, Outlook won’t send or receive. Review storage and free space if needed. You can see Mailbox storage limits in Outlook - Microsoft Support
4. Check the Outbox folder in app
If messages are stuck in Outbox, close Outlook, reopen it, then try sending again.
5. Restart Outlook in safe mode:
- Close Outlook completely
- Press Windows + R, type outlook.exe /safe > press Enter
- Try sending/receiving in Safe Mode
If it still fails, to help me guide you more precisely, please share:
- Which specific steps have you already tried?
- The exact error when trying to send/receive (e.g., bounce/NDR text, “quota exceeded,” or “account blocked”).
- Whether the problem occurs on Outlook.com web, the Outlook app (New Outlook or Classic Outlook), or both.
Once I have a bit more information, I can provide the exact fix for you.
