If I click the option in AD "User must change password at next logon" then I cannot login owa.
Exchange 2010, Win2008 Sta SP2
In II7, owa authentication is "Basic Authentication". If I unclick the option, then I can login and change password is fine as well.
I google that it is a problem in win2k3 + exchange 2003. Not know how it happen in the exhchange 2010.
