"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Check the bindings in IIS. I have seen it have an issue when it has 127.0.0.1 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).

But this error is only with one account, with other is no problem.

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.
