We have two domains in separate forests, One forest has Exchange 2013 server, how do we get a constantly up to date Global Address list of users from the "Other" forest?

Thanks.

Hi Babu,

You can use a 3rd party tool such as GALsync or you can check the below link

A few possible solutions:

1. Microsoft Forefront Identity Manager (FIM)

2. 3rd party product like GalSync

3. Write some script to do export and import

Hi,

We can configure Global Address List (GAL) Synchronization with Forefront Identity Manager (FIM) 2010:
