If you use a Palm Tungsten T or E, and other PDA's, the Entourage conduit is not compatible and will not allow you to sych your handheld with Entourage. This is a serious flaw if you use Entourage as your primary address, emal, calendar and to do list application. Microsoft is completely aware of this and offers no excuse. They simply state that the Entourage conduit will not work and they have no solution for it.In Office X the Entourage conduit worked flawlessly.
