I have an Exchange 2007 server (installed on Windows 2003 64-bit) that is being reviewed for the installation of CRM 4. CRM 4 will be used by a handful of mailbox owners on this server. I would like to know if anyone with experience using this application have any issues with these two services being installed on the same server? My concern is that the application will utilize too much resoures for the few mailboxes that will fully utilize the CRM service. Or it will give a mailbox access to a CRM service that should not have the service. The documentation I received was to update the server with the following: .NET 3.0.4, MS C++ Runtime v8, Microsoft Application Error reporting v 11.
