I have finally given up on the native Exchange client. If it would keep my trash folder synced so I don't end up with 1000 emails to manually delete, I might even deal with it. Unfortuanatley it just doesn't happen.
So, I have tried Touchdown, it is a really nice Exchange client but I really want an integrated in box so that I can see everything in one place. (are you listening NitroLabs? Add IMAP Support)
Now I am on K9. I have not had any luck getting it to work with the 1and1 hosted exchange. Has anyone done this? How is it working for you if so?
