Dear Experts,<o:p></o:p> Currently we have a Exchange 2010 SP2 Enterprise (2 HUB/CAS and 2 MB with CAS Array and DAG ) organization .

There is any possibility to implement two isolated GALs for these companies ?<o:p></o:p> 2. Whats the best method to host two different companies in a single Exchange 2010 SP2 Enterprise organization? <o:p>3.In implementation stage we can expect any issues in current production ?</o:p> Thanks in advance Regards<o:p></o:p> CK<o:p></o:p>

Address Book Policies rather than address list segmentation or hosting is what you'll look to: http://www.jaapwesselius.com/2012/07/09/msexchquerybasedn-and-exchange-2010/ http://technet.microsoft.com/en-us/library/hh529948.aspx >2. Whats the best method to host two different companies in a single Exchange 2010 SP2 Enterprise organization? That depends on what your needs are. Must you keep the two sets of mailboxes separated? Must they both have public folders? >3.In implementation stage we can expect any issues in current production ? You should always expect "issues" when introducing something new.
