I'm very much interested in the improvements MS has made with IMAP in Outlook. Apparently they really worked on it to make the experience better.
If they have, I can't tell and I've been running Outlook 2013 for months. IMAP is still slow, buggy, doesn't push, and when new email arrives you get a toast notification ... but nothing in Outlook is bolded.
On the plus side, if you have an Outlook Anywhere connection (Exchange RPC, etc.) your username/password are now remembered properly.
