"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

To find the objects with Exchange attributes, use the Active Directory Users & Computers snap-in.
1.  Run Active Directory Users & Computers.
2.  Right-click your domain at the top of the tree and click Find.
3.  Click the Advanced tab and then choose User from the Field button.
4.  From the list of attributes displayed, choose Exchange Home Server.
5.  Set the Condition field to Ends With and then type the name of your Exchange server into the Value field.  Click Add to add this value.
6.  Click the Find Now button which should now display the problematic objects.
The Exchange attributes can now be removed from these objects and the uninstall process attempted again.

It did seem to complete but is it a clean uninstall?

This is what the final window says (see attachment).
Its not a clean uninstall. If it clean you wont see the exchange 2003 application in add\remove programs.

Can you click on the exchange component on the above error message and paste the output of the error message.

I found a KB on how to remove exchange 2003 manually. That went smooth but exchange 2010 thinks the old server is still there. All routing connectors are removed. I found two administrative groups in ADSI. Can I remove the first storage group that I think use to belong to the old server (see attachment)?
If you have completely removed exchange server 2003 (first administrative group) from your exchange server organization. So you can manually delete it.

Now my public folders have disappeared. They were there yesterday. I'm getting the set of folders could not be opened.
we don't have any reference with exchange server 2003, since it is removed from exchange organization and removing the first storage group and component wont affect exchange server 2010.

Are you having any issue with the public folders now?
