I am trying to decommision an Exchange 2003 server in my organisation, all mailboxes have been moved as well as public folders (systems+data) and I also removed the system attendant mailbox as per MS KB articles. No luck removing the server from add/remove programs as I always get a message saying "one or more users currently use a mailbox on this server ....." so I decided to remove it manually using Microsoft article 833396. After this, I wanted to remove the server from active directory but when I try to remove it from System Manager I get the following error message again:
The Server "NALONSRV04" cannot be removed because:
One or more users currently use a mailbox on this server. These users must be moved to a mailbox store on a different server or be mail disabled .....
facility: Exchange System Manager
ID no: c103f492
I searched using "AD Users and Computer", LDP.EXE and LDIFDE for hidden mailboxed but I cannot find anything bound to this server anymore, I don't understand.
I am really becoming obsessed and frustrated now as I would like to clean Active Directory properly from this server, I don't think using ADSIEDIT would make by deleting the server entry, would it?
Any advice is really apreciated
