Hi, We are looking to move to Exchange 2007 and I was wondering what the minimum server roles were required to get things up and running - would it be Hub Transport, Client Access and Mailbox? Can these roles all run on the one server are would we be best seperating some of them and sucurity/performance etc. reasons? Thanks, D

Yes , these roles can be on the same server. How ever , it will be better if you can atleast seperate the CAS and HT on a different box.Raj

Hi,To make Exchange 2007 work normally, the minimum server roles are Hub Tranport, Client Access and Mailbox Server. And you can deploy three server roles on the same server.Frequently Asked Questionshttp://technet.microsoft.com/en-us/library/bb123811(EXCHG.80).aspxThanksAllen
