It is more an Outlook + Exchange thing v. IMAP
Outlook + Exchange are joined at the hip and their native communication protocols are MS proprietary, not standard. IMAP, OTOH, is standard and so has to work across a swath of mail servers with varying capabilities.
MS has never quite gotten a handle on the problems with Outlook's local mail stores. If you leave everything on the server, things work well. Enable syncing to local storage and things are bound to go off the rails. (And it is not limited to mail stores, the Global Address List is obnoxious too if local sync is enabled.)
