email account not showing Alert: forward_with_same_id_exists [info@mysite.com]

[befree22]

I created several email addresses for my website. However, one of the emails isn't displaying in the list of mail accounts. I keep getting the following error when I try to add it so that it appears in the list:

Press Esc to close    
Alert: forward_with_same_id_exists [info@mysite.com]

FYI: I looked in forward emails for the email address but there is none. The email exists somewhere in KloxoMR database but not in the mail accounts list.

What command do I run to fix this problem?

Try go to 'all mail forwards' to know about it.
