Hi Team,
We have an Exchange 2010 and Exchange 2013 coexistence and we are migrating mailboxes from Exchange 2010 to Exchange 2013. The problem is after migrating the mailbox of the user to Exchange 2013, the GAL is not available in his/her outlook 2010. But it is still working before when the mailbox is still in Exchange 2010. Is there a way we can replicate the GAL from Exchange 2010 to Exchange 2013. Hope you can assist me on this. Thanks.
