I have two offices on either side of the country (one main, one branch), sharing the same Domain via a VPN. I want to install Exchange 2010 on the branch office domain controller, everyone there currently uses Outlook Anywhere to connect to the exchange 2007 server at the main office. What server roles do I need? All I want to do is move the branch office users mailboxes to their local server, for them to be able to email large files to themselves or local clients without it having to go back over the VPN to the main office first. Do I need the client access role if its installed on the other server? Can they just use the webmail interface at the main office to view their emails if they need to, or will it only work for mailboxes on the server with the Client role installed? Do I need hub transport as well? Regards, Alex

DO I need a CAS array if I won't be utilising DAG, as they are both standard editions? Can I use a self signed SSL on the 2nd Exchange (at least in the shortterm)? They will rarely need to use webmail or Outlook Anywhere. It would be a hassle revoking the SSL at the main branch. Regards, Alex

Hello, do you have the option to install Exchange 2010 on a member server of the branch office? It's not a best practise to install Exchange on a domain controller. Greetings, Toni

Greetings, Toni Completely missed that. If you installExchangee on to a domaincontrollerr then it is going to have an impact on the other Exchange server. Exchange will only use thedomainn controller that it is installed on. If you have other Exchange servers then they will ONLY use that same domain controller as well, which will mean Exchange in your main office will only use the domain controller in the branch office - and therefore there will be performance issues. You need to put Exchange in the branch office on a member server, not the domain controller. Simon.Simon Butler, Exchange MVP Blog | Exchange Resources | In the UK? Hire Me.
