Same thing happened to me (1and1 hosted Exchange). It was working fine with 1.1. After the update to 1.2 I noticed that nothing was syncing. So I removed the account and figured I'd add it back to see if that fixed it. Only now it refuses to validate the incoming mail server. I'm stuck now and have no way of adding it back. My account settings are correct and verified. The account itself is fine (works from desktop without issue).

I have confirmed that the Pre is actually reaching the server because if I change the server name, I get a different error: "Unable to connect to incoming mail server."
My IMAP accounts work fine (Gmail and Fastmail).
Anybody else having this problem? If so, which provider are you using? Maybe if we compare notes, we'll find a common cause and solution.
