I have an 8800 issued from work and I have my work email account setup through an Enterprise Server. I also set up my aol and gmail account through the Personal Email Setup function. Everything works great except that when I get an email in my AOL or GMAIL account, I also recevie that email in my work account.
They show in the messages folder. That is the way it works. The messages folder is a 'catch-all' folder. It will get all messages (from any address), call logs, text messages, etc.
