Hello,
We have Office 365 with ADFS and Dir Sync enabled. We are running SBS 2008 and manage Exchange locally on the SBS and then it syncs up changes to 365. The problem is that we want to kill off the SBS 2008 and move forward with Windows Server 2012 and not SBS as we are growing. How should we handle the Exchange component of the SBS? Moving DC roles, files, apps is not a problem. From what I have seen, if we uninstall Exchange, we will have make email changes from ADSI Edit. We would rather not do this, but want to keep SSO capability.
