Hi there, I have two servers Server#1 and Server#2. Server#1 has E2k7 installed ( i.e three roles Hub Transport, CAS, and Mailbox server). Server#2 has Windows server 2003 SP2. Now I want to remove Mailbox Server role from Server#1 and install Mailbox server role on Server#2, which nor has Active Directory installed, nor is the member of my domain fabrikam.com. Plz specify the steps to first remove Mailbox Role from Server#1 and then install it on my new server Server#2. Do I need to install Active Directory on Server#2 before installing Mailbox Role. best regard, Cyber Friend
