Have a client that I have started migrating from SBS 2003 to W2012. I have joined the W2012 to the somein and it is setup with A/D. Originally I was going to decommission the SBS2003 completely, moving the FSMO roles, remove Exchange and decommission. Now he is setting up a remote office and I would like to keep the SBS2003 machine at the original office for A/D authentication but have most of the files on the new server at the new / larger location.

What is the drawback to removing Exchange from SBS2003, but leaving it run?
Only used for the A/D component for local authentication. He has migrated mail to Office365 and only has 6 users. 4 at new location and 2 at old

* Assumes that a new, functional exchange-server is in-place prior to decommissioning of this email server - which should be the case since the client is now on O365*

The drawbacks should be minimal, if the removal procedure is performed correctly.
This guide explains the process in detail to help minimize possible complications.

Exactly what I planned and was hoping for.. Have the Install Disk 2 ready to drop and and then uninstall.

Well I think you're failing to take into account that Server 2003 has been unsupported now for more than 6 months and has high risk for security flaws, etc.  It really needs to go.   You should really consider replacing it with Server Essentials 2012 R2

I'd agree with Cris here.  Don't do this.

The last thing you want is to do is continue supporting the 2003 if you don't have to. If he wants a remote office then either configure a VPN or get another Server for that site.

He has new W2012 server at new site. Thought there may be advantage to keeping old server in place for authentication only.. But there will be vpn between two offices. Old office will be in his home with only him connecting.. But I guess I could take it out and just rely on VPN

Running on obsolete server software puts server data and end user at risk
