I have an exchange 2007 installation with all the roles in seperate servers , 2 edge , 2 cas , 2 mbx.
So, i have a specific user in an organization that he can't login with IMAP . He takes an error about wrong password . From OWA he logins successfully , with POP3 also successfully but with IMAP i take that password is incorrect. All other users in this organization work without any problems. Only this user has the problem.
I also try restart IMAP services in both CAS servers but problem not solved.
