Is your .NET framework 2.0 and 3.0 updated to SP2?
And just in case there was confusion..I wasn't referring to "Allow unsupported devices" but "Allow Non Provisionable Devices".
My settings on the droid were:
domain\username
password
mail.******.com
While I originally had 'Use secure connection (SSL) checked and I could sync, I was unable to view attachments. After unchecking, attachments worked as well.
Really, I tried every possible combination like you did only to have a few optional SBS updates do the trick.
Have you seen these?
