I've got one user with office 2k3 on a new dell installed laptop who uses pop w/ exchange 2000. Everything works fine for a while, but after a couple of days of use it no longer accepts his password...he can try 20 times and never get locked out (policy is 3 to lockout). So i'm thinking his credentials aren't being passed along to the mail server at all. OWA authentication works great. POP works great for everyone else (albeit on older versions of Office). Anyone seen this or have any ideas? oh yeah..i also tried IMAP...same problem. Thanks! John Knightly
