  3. Incorrect or misspelled recipient’s address: This is a common mistake when you’re typing in an email address. Be sure to double-check the address before you hit send!
  4. Wrong outgoing mail server: If you’re using a third-party email program or app, ensure that you’ve entered the correct outgoing mail server settings.
  5. Mailbox full: This error can occur if the recipient’s mailbox is full or exceeds their allocated quota.

How Do I Fix Delivery Failed To These Recipients In Hotmail (Outlook)?

If you’re getting delivery failed messages when sending to specific recipients in Hotmail or Outlook, there are a few things you can do to try and fix the issue.

Check If The Recipient Is Blocked

First, check if the account is blocked. If it is, you’ll need to unblock it before you can continue sending messages. 

  1. To do this, go to and sign in to your account. 
  2. Click on the gear icon in the top right corner, and select View all Outlook settings from the drop-down menu.

3. Next, go to the Mail section from the left side.

4. Here, click on the Junk email option.

5. Now, check if the recipient you want to mail is blocked under the Block senders and domains section.

6. Click on the bin icon right next to their email to unlock them.


7. Once done, click on the Save button at the bottom right corner.

Check If Your Account Has Been Compromised

If you think your account may have been hacked, change your password immediately and run a malware scan on your computer. 

You can also check for any suspicious activity by going to your account settings’ Recent Activity section. If you see any unfamiliar activity, it’s good to change your password and enable two-factor authentication for extra security.

Check If The Email Is Correct

If neither of these solutions solves the problem, there is likely an issue with the email address. In this case, you’ll need to recheck it with the recipient and use the correct email.

If nothing else works, restart your internet or your PC.
