Sending, receiving, and organizing email in Outlook.com
Hello,
I will walk through a few steps with you. Some of these are just to help figure out what is wrong, not to fix it right away. So if nothing changes after a step, that is normal. I will keep going until we solve it.
Please send a test email from one of your other accounts to the problematic one. If a bounce-back message is received, please send a screenshot of it.
Our next steps depend on the bounce-back message that is received.
I look forward to hearing from you to get the results of the troubleshooting.
