I've been pulling my hair out on this one for a few days now.
I have 1 user that when she connects directly to the exchange server via RPC everything works as expected. When she connects to the exchange server via RPC over HTTPS with her credentials she gets a unable to open mailbox error (cached mode is currently off). If I use someone's credentials who has rights to her mailbox I can get in with out a problem.
I have created a brand new user, who is only in the domain users group, given that user full rights to her mailbox I am able to open her mailbox over RPC over HTTPS.
If I put the affected user into the domain admin group, everything works fine.
I've compared permissions, group membership and done anything I can think of except for blow the mailbox or her user account away. Neither of which I really want to do as she is a remote user and doesn't come to the office very
often.
