Address book synchronization between GroupWise and Exchange enables users of both email systems to easily select each other from their native address books.
In addition, address book synchronization is a prerequisite to the exchange of calendaring information between GroupWise and Exchange users, as described in Section 3.0, GroupWise Free/Busy Service.
IMPORTANT:If you are already synchronizing data between your GroupWise and Exchange systems, see Section A.0, Preexisting GroupWise/Exchange Synchronization.
