I tried the repair folder trick, and it seemed to work. But the operation reset the folder settings; I like to see additional columns such as "Recipient". As soon as I set that, I noticed the issue started again.
Win7 (all updates applied), x64. Sorry I didn't test on a new profile, and the timing of my change and noticing the issue may be coincidental. But I figure every bit of info may help you.
What also should be mentioned, is that there are known IMAP problems with recent version of MS Exchange. So much so, I ended up installing the DavMail gateway.
