So got a new iPhone, get vpn up and running without a problem. Also managed to get the mail client to talk to my exchange server.

The problem? We have a couple users this is not working for it seems if you rename a user in exchange there actual mailbox store keeps the same old name, Every single person who's login does not match there mailbox store name can not use IMAP4 to check there email it just dies for some reason..

If anyone has a possible solution short of deleting and re-adding the user which takes a ton of time since we also have to export and import all there settings let me know.
