Following MS Outline for upgrading to Exchange 2000 in 6 steps, all ran smoothly. Public folders and Private folder mailboxes were moved to the new Win2k server without problems about 2 weeks ago. Exchange 5.5 box is still running and appears within Routing Groups as a Member Server with the Internet Mail Services Connector showing. Can I just decommision the 5.5 box via Exchange Administrator 5.5 after deleting the connectors in the Exchange 2000 System Manager? And have Internet e-mail routing continue to work without a problem? In other words, hasn't all SMTP address/info flowed automatically to the new 2k Protocol from the old box during the upgrade, or am I missing something and if so, what else do I need to do?
