I have 3 computers. They have Office 2010 and 2016. For the last 3 months I have been getting e-mails that are not addressed to me. They are bellsouth.net emails. I have several bellsouth.net emails along with gmail addresses. All my addresses are working fine for all my addresses to send and receive.

The email address is ANDREWCOW@BELLSOUTH.NETt, rellemon@bellsouth.net,ANDREWCOWN@bellsouth.net.

They appear to be from legit companies E-Bay, Edward Jones, etc.

These emails do not exist in my outlook Email Accounts and of course, I can't block them because they are from different companies. There doesn't appear to be away of blocking other people's email from entering you mailbox.

If I send something to these e-mail addresses above, they come back with a failure notice. Addressee unknown

I called AT&T and they were of no help. Just told me to ignore them. I have Googled over and over again and nothing comes up similiar to my problem.

Since I have 3 computers I have currently deleted all bellsouth.net Email Accounts except for my Main one. I would hate to lose that as I have used it for 20 years.

I have not tried changing the password on the legitimate accounts. All of these emails and Outlooks have been set up for a very long time and this started approximately 3 to 4 months ago.

I was wondering if one of the bellsouth.net addresses is corrupt. My next step will be to delete all of them and put them back in again one at a time.

I have Windows 10. Any suggestions would be very helpful.
