Hello everyone, I got the follwoing situation: Exchange 2007 with SP2 on a Windows Server 2008 R2 - I know this is not supported and I don't know how my client managed to install this anyway. The problem is that I can't update to SP3 nor can I uninstall the whole Exchange while migrating to a second, clean Exchange 2007 with SP3. When I try to manually update to SP3, the Setup fails, telling me that "setup.exe" and "exsetupui.exe" are blocking files. I set up a second server with Exchange 2007 SP3 and did a full migration to the new server. I then wanted to uninstall the Exchange with SP2, but the uninstallation fails with an error message, that Exchange SP2 is not supported under Server 2008 R2. Does anyone have an idea how to gracefully get rid of this Exchange SP2 server?
