Hello, We are planning a deployment of 2 servers (without DAG) with exchange 2010 standard. We thought about one CAS server, and one Mailbox and HUB server (both to them virtual machines), do you think is the "best" configuration for it? thanks in advanced, any suggestions will be apreciate

Ok, thanks for all. This is in the process of migration from one Exchange 2003 server to the 2 exchange 2010 servers mentioned. Looking at official documentation, its said that when you deploy the CAS server, automatically a connector is configure just to flow mail between the 2 servers (legacy and new one). But, the mail will going working without configuring anything more?, just only from the legacy ones, i mean. Is there no impact when i deploy the CAS server with exchange 2010?, Outlook 2003/2007 will continue working at that moment without problem?... thanks in advanced
