We have 3 sites , The main office is BTech.co.za The branch office from one region is BCur.co.za and the other one is Aloe.co.za, We want these branches now to work together not independently that is mail should be received from main office, Active Directory should be replicated through to all these sites,, We are trying to a centralise administration. Now my question is which is the best strategy to implement because we want these branches to get mail from the main office. Thanks
