anyone have issues with K-9

I recently updated to fresh 2.1 from fresh 1.1 and loving the rom, but I'm trying to find a quick solution to my email issues.
works exchange server is Outlook 2007, and I have subfolders that I would like to be notified when I receive emails in these subfolders without having to manually go into each one and sync.
I installed K-9 and kinda have it working, I get errors checking mail but it will send mails?
any thoughts
