I have a client who want to migrate to Exchange 2013. His organization is Exchange 2010, and they decommissioned all exchange 2007/2003 services a while ago, however MS recently ran a tool and they found some legacy exchange components in AD that exchange still makes reference in BPA
Is there a free tool that we can use to clean all exchange legacy components in Exchange 2003/2007?
Can you please summarize all steps to delete all legacy Exchange 2003/2007 components from AD using ADSIedit tool or any other OS built tool?
What entries/DNS/objects/resources should be deleted?
