If you installed the GroupWise/Exchange Coexistence solution in your GroupWise system, you must follow the instructions in Configuring the MTA for Address Book Synchronization
in the GroupWise/Exchange Coexistence Guide after you upgrade the MTA that synchronizes users between GroupWise and Exchange. This enables you to see the external GroupWise objects in the GroupWise Admin console.
No other changes to GroupWise or Exchange are required to continue using the GroupWise/Exchange Coexistence solution with your GroupWise 2014 system.
