Can't uninstall Exchange 2003
Posted on 2012-03-14
Hi, we just migrated from Exchange 2003 on a Server 2003 machine to Exchange 2010 on a 2008R2 machine. Everything has been successful, but I am unable to uninstall Exchange from the 2003 box. When I go into control panel, add remove programs, Microsoft Exchange, Change/Remove, when I go to change the action for Microsoft Exchange to remove, I get the following error message:
"Setup encountered an error while checking prerequisites for the component 'Microsoft Exchange': 0x80072030 (8240): There is no such object on the server."
If I selecect Change instead of Remove, the Next button remains grayed out.
My question is:
1) Do I need to uninstall Exchange from this server to have it removed from the network and gone from Active Directory?
2) If I do, what do I need to do?
3) If I don't need to uninstall, what steps do I need to take?
Here is what I have done to prepare for the uninstall:
a) Moved all malboxes off the old server and deleted system mailbox users
b) Moved public folders to Ex2010
c) Dismounted the Public Folder store
d) Deleted public folders
e) Moved generation of OAB to the new server
f) Deleted recipient update services
g) Removed the routing group connector to the Exchange 2010 machine
Thanks in advance for your help.
