Windows Mobile 5.0 and Exchange 2003 SP2 hate each other - HATE - Support code: 0x80070002

At least, they do tonite for some reason... even though they are designed to work together.
Recently upgraded my PDA from Windows Pocket 2003 SE to Windows Mobile 5.0 aka Windows CE 2005...

Used to be able to download e-mail, not anymore!

No siiir... I've completely wiped the ROM/RAM, reset everything, redownloaded certificates, tried the back end server, the front end server, tried it unencrypted.. can't get the thing to sync... in the cradle, over wifi, over bluetooth.. nothing. I know WM5 has restrictions when it is outside of the cradle, I don't care, as long as it works in the cradle.

It's a Dell Axim X50v if anyone is curious. I don't want to go back to 2003SE, because that means I've admitted defeat.

[edit a few days later: Looks like a lot of people are having the same problems]
