I have a user in New York that accesses his E-mail via OWA. All works Well, with that said when i tried to set up his outlook 2007 client it would not work. kept asking for username , password.
So what i did is i went to a prompt telneted server 110. connects fine.
type user "username"
then get the following: -ERR Logon failure: unknown user name or bad password.
with that said if i use my username from his computer through telnet i have no problems.
I have gone a step further to try it internally via the internal IP and the exact same thing happens.
All i can figure is something is messed up on my exchange server. any ideas.
