I am still trying to get this dialog box from popping up every time the eM client polls my ISP. I removed "Aimail" mailbox.

I am still trying to get this dialog box from popping up every time the eM client polls my ISP. It’s ruining an otherwise perfect experience using this email client. It happened when I eliminated a few mailboxes including “airmail” which I don’t have any idea what that was or why I need it.

The easiest way to resolve it is to remove the email account from eM Client, then add it again.
