I will be deploying a new Windows Small Business Server 2011 to a business with about 30 workstations this weekend. Unfortunately, the email solution(s) this particular business is currently using includes a mix of about (6) hosted Exchange accounts and (25) basic POP/IMAP accounts purchased through their ISP. Due to the complexity and time requirements of the server installation, migration and workstation joining, we will not have time this weekend to pull down all of their mail and make the switch to onsite Exchange at the same time. We will, however, be making the switch within the next 30 days.
We will be using ProfWiz to migrate their local profiles into their new domain profiles. They did not currently have a DC in-place. In my experience, when joining workstations to a SBS, Outlook wants to connect to the local Exchange server to handle mail. I want to avoid this for now. My main fear is that I will have issues with their existing mail profiles after joining each workstation because the new SBS will want to configure their mail profile for use with the local Exchange server.
I figure there must be other techs out there that have had to stagger the SBS install and the Exchange migration with an existing hodgepodge of email profiles on local workstations for one reason or another. I would love to know how you have handled this situation or get some ideas from my fellow techs on how to avoid serious mail profile problems during this install.
Thanks a million.
