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.
