I upgraded from Exchange 2003 to 2010 several years ago. I thought I had properly decommissioned the 2003 server but it still comes back to haunt me now and then.
Recently I noticed the following:
- I go into EMC 2010 and create a new distribution group
- During the setup of this group, I can specify the expansion server
- If I 'browse', a list pops up. I see my OLD (2003) Exchange Server as well as my new (2010 Server)
How can I remove this 2003 server from Active Directory once and for all!
For all I know it's causing other issues.
