Check the bindings in IIS. I have seen it have an issue when it has as its own https binding. Remove that and the http one and try again. (easy to add back if theres a problem, so not a drastic change and works most times).

Export all the mail to PST on a machine that has a current Anti Virus, purge the mailbox from exchange, and then re-create the user's mailbox from scratch.
