I am deploying Exchange 2007 CCR environment from scratch. I just have some questions regarding to witness file share server.
As I know, there is the required servers for Exchange 2007 CCR
* Do I have to install Hub Transport role and Client Access role into Witeness file share server?
* If Yes, how can I install only Hub Transport role and client Access role in the server? is it just to choose this two roles during exchange installation? any specs for this two roles?
* If no, when I install exchange 2007 in both cluster nodes, if I choose "Active cluster mailbox role" Does it mean only mailbox role, not other roles will be installed?
* If Hub Transport role and Client Access role have to be installed into witeness server, how can I do the HA for this two roles? Do I need to have two witeness servers with this two roles? How failover can be configured between this two witness servers?
