I have recently migrated to Exchange 2007 and I have a question on the Mobile Services. In Exchange 2003 I had to setup Mobile Service for each of the cellular vendors that the mobile devices connect through. I don't see anywhere within Exchange 2007 to set this up again or where they transfered from Exchagne 2003. Does E2007 no longer use these? I would hate to uninstall E2003 and loose those settings.
