We have installed Exchange 2007 on new server. Having a problem with a Pocket PC running Windows Mobile 6.0 Pro not able to send out email after moving it's mailbox over from Exchange 2003. Emails that are sent out are somehow getting stuck in the Draft folder on the Exchange 2007 box. I have been able to get another user account working with a different phone (Sprint). So it seems that it's something related to the Pocket PC but I can not figure out why. any help would be appreciated.
