Rumor has it: Microsoft is about to release quite soon a service pack for Microsoft Exchange Server that will offer improved push technology. Currently push technology in Microsoft Exchange Server sucks

[Mark Rejhon]

Just to clarify, Motorola has to choose a push technology quickly and they are supplying this by using RIM Blackberry push technology rather than the Exchange server because Microsoft has not yet provided this rumored service pack. So essentially, the Motorola Windows Mobile phone will be using Blackberry's solution rather than the Microsoft Exchange Server solution.
