I just installed a new exchange server 2010 with server 2008 64 bit. All users can connect to the active sync via there iphones/android devices i have one user that it keeps saying cannot connect to server.
But, if I change his password to the "wrong" password it tells me the password is incorrect!! His account is enabled for activesync I have double checked that via the GUI interface. I have tried his account from a working phone as well to verify that its nothing to do with the phone. The phone will also connect to other accounts perfectly so it has to be something with his exchange account any thoughts??
