Thanks, I actually found it the hard way this morning using LDP and the manual search method. J Turns out whomever did the 5.5 to 2003 migration uninstalled the ADC software, but didn't delete the connection agreements first. So, when exploring under "CN=Microsoft Exchange, CN=Services, CN=Configuration,DC=domain,DC=org I found an entry for the Active Directory Connector. Renamed it (just because I always get twitchy deleting outright from LDP or ADSIedit if I don't know for sure what it is I'm deleting), and voila... Oh well, live and learn.. (Now, to call up and make fun of my friend who did the migration..)

I would query your AD to see if there are any references of any store information in AD. Export all information for your exchange config partition in AD, then search through the text file for the name of the store that shows up when you create a mailbox. ldifde -f c:\exchange.txt -d "CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=fabrikom,DC=com" -p subtree James Chong (MVP) MCSE | M+, S+, MCTS, Security+ msexchangetips.blogspot.com _____ From: exchangelist-bounce@xxxxxxxxxxxxx [mailto:exchangelist-bounce@xxxxxxxxxxxxx] On Behalf Of James Lilly Sent: Wednesday, August 08, 2007 3:31 PM To: exchangelist@xxxxxxxxxxxxx Subject: [ExchangeList] Weird AD/Exchange issue One of my clients has a weird issue: This is an Exchange Server 2003 server, and whenever we go to add a new user through AD Users and Computers, an old Exchange 5.5 server and Private Information Store shows up. I see nothing in Exchange System Manager referencing the new server, and if you try to use the Move Mailbox wizard, it doesn't show up their either. It ONLY shows up on the Exchange dialog box to create an Exchange mailbox. There are no traces of Exchange 5.5 I can find anywhere (no SRS, no ADC, the server has been off for over two years, etc., etc.) Where is this coming from, and how can I get rid of it? Any ideas?
