Solutions to Terminate SBCGlobal Email Error Code 550

Given below are the troubleshooting solutions that you can perform step-by-step to eliminate error code 550 in the SBCGlobal email account;

Solution 1. Double-check the recipient’s email address

If you are typing the recipient’s email address in a hurry, there is a higher possibility of typing errors. Therefore, we suggest you double-check or verify the recipient’s email address is correct and that there are no misspellings.

Apart from this, you must also re-confirm the email address with the recipient, as the recipient might have given you the wrong email address.

Solution 2. Resend the Email After Sometime

Possibly, the recipient’s email server is temporarily down due to several major reasons. In that case, you must inform the recipient that the server may be down and ask them for an alternative email address, or instead, try waiting for a few hours until the server issue gets eliminated and try again later.

Solution 3. Fixed The Blocked Authentication

If the SMTP settings or authentication is incorrect, you may face various issues in sending new emails. Therefore, you must double-check that the authentication is not blocked;

  • Firstly, launch the email application, and check the SMTP authentication settings.
  • Thereon, check mark the box next to the “My Server Requires Authentication” option.
  • Moving ahead, you must set up an SBCGlobal email account with any third-party email application, and then the authentication process will start automatically.
  • Once the authentication process ends, click on the “Yes” option to confirm the configuration.

Once you are done with the steps mentioned above, verify if the SBCGlobal email error code 550 has been terminated. In case the error persists, then try the next solution.

Solution 4. Check the Email Account Blacklist Settings

If you have added the recipient’s email address to the blocklist, it might disallow you to send new emails to that specific email address. Therefore, we suggest you check the blocklist settings on your SBCGlobal email account.

Remove that account immediately if you notice that the email address is added to the block list. This step will enable you to send or receive new emails from the email account.
