It has been brought to my attention we are having trouble with our OWA access from outside. When I try to use it with my username and password, it won't take it. The authentication login will just keep popping back up then eventually it says access denied. Sometimes I'll get in and see my emails, then when i click on one to read, it will want me authentication again and won't take it. I am 100% positive i am entering the correct username and password. It does it with all other users as well.
using exchange 2003 SP2 on Windows server 2003 R2 SP1
Using outlook internally is fine, along with internal OWA is fine as well.
