I have an existing 2003 SBS which I am trying to decommission. My ultimate goal is to install a fresh 2010 and just move the mailboxes.
I have a new Server 2008 Standard with a failed Exchange 2007 Standard installation which doesn't show up in add/remove or even program files anywhere, but the 2003 SBS can see it. I've been struggling for weeks to find a way to remove it, including trying to reinstall and then remove, and following TechNet instructions for removal. Any ideas? Thanks in advance, Mark
