Hotmail issue

Question

I have a major problem with my hotmail. I cannot send out but receive. For a few days anything sent has had the following ‘your message wasn’t delivered because the recipient’s email provider rejected it’. I have had assistance from APPLE who has tried by deleting my hotmail account and resetting it, but still it isn’t working. Please advise as soon as possible if you have managed to rectify this problem.

Hi Diannem

It seems like your account is in some flagged list. Do you have the complete bounce back message handy?

It would help a lot in investigating the issue.

I’m eager to hear back and work together to find a solution.

Answer 2

The error “your message wasn’t delivered because the recipient’s email provider rejected it” means messages are leaving Outlook.com but are being refused by the receiving email systems. This is handled on the server side and is not fixed by deleting/re‑adding the account on Apple devices.

Use these steps:

1. Confirm account is not blocked and storage is not full
   • Sign in to Outlook.com in a browser.
   • Check that the mailbox opens normally and that there are no prompts about unusual sign‑in activity or account blocking.
   • Check Microsoft cloud storage and mailbox size; if storage is full, sending is blocked and messages to you will bounce. Follow the guidance in “Can't send or receive email in Outlook.com” to verify storage and account status.
2. Check the exact non‑delivery report (NDR) text
   • Open one of the “delivery failed” messages in Outlook.com.
   • Look for any of these patterns in the error details:
     • “Can't connect to remote server/message expired” or “Connection timed out” – this usually resolves on its own; wait and resend later.
     • “Errors that include ‘blocked’ or ‘listed in’ and references to sites like ‘spamcop,’ ‘dynablock,’ ‘blackhole,’ or ‘spamhaus’” – this means the recipient’s server is treating the Outlook.com server or account as spam.
3. If the error mentions “blocked”, “listed in”, or spam/blacklist services
   • This indicates intentional blocking by the recipient’s email provider.
   • The documented resolution is to contact the support team for the recipient’s email provider and request that the account or sending domain be unblocked.
   • If this affects multiple recipients at the same provider (for example, all addresses at the same company or ISP), that provider’s support must remove the block.
4. If the error is “Out of memory”, “Resources temporarily unavailable”, or similar
   • These are temporary issues on the recipient’s side.
   • The guidance is to wait; if the NDR says the recipient’s provider will keep trying, no action is needed. Otherwise, wait a short time and resend the message.
5. If the error is “Undeliverable” or “Your message couldn’t be delivered”
   • Verify the recipient address is correct and current.
   • Reduce the number of recipients in a single message.
   • If sending from an app (Apple Mail, Outlook for Mac, etc.), try sending the same message directly from the Outlook.com web interface to see if it succeeds.
6. If none of the above resolves the issue
   • Use the Outlook.com in‑product Help to reach support:
     • Sign in to Outlook.com.
     • Select Help on the menu bar and describe the delivery failure.
     • If self‑help does not solve it, scroll to Still need help? and choose Yes to start a support request.

These steps address the documented causes for Outlook.com mail that is received correctly but rejected when sent.
