Outlook 2007 irritations

Why do I keep getting these? They rarely happened in Outlook 2003.

A data file did not close properly
I promise you, I did close Outlook properly. Just like I do every time. It’s good that this version can do the integrity check in the background, but I don’t see why it’s needed at all.

A connection to the server cannot be established
IMAP performance in this version is appalling. It rarely seems to stay connected to the IMAP server for more than a few seconds at a time. Just about all the time I need to keep reconnecting and/or do the Mark For Download / Process Marked Headers thing, which gets old really fast.

I like a lot of the other stuff in the new Outlook, but these are very irritating.
