I am a new Mac user and am trying to setup the mail app to connect to my exchange 2003 mailbox at work, but it is telling me that the log in failed and to verify the username and password. All the info I put in is correct and have IMAP enabled on the server but still cannot connect. I then created a new user in the exchange at work and setup the new user on the mail app and it was able to connect with no problem. Can someone please tell me why I am able to connect one user but not another user, is there some setting on the older user I need to change? Any input will help, thanks.
