In this post, I will showcase the steps you need to follow to decommission or uninstall the first Exchange 2003 server in your organization. You will get into this situation if you are migrating from current server to a new server on the same version or have transitioned to the next version.

Offline Address Book

I have not been lucky enough to avoid this message whenever uninstalling any Exchange 2003 installation. There are multiple ways/options to find out the culprits, however following is what always worked for me.

Open ADUC, Select the domain and click on Find.

In the Find Window, choose Custom Search in Find option, click on Advanced and use the following query.

(msExchHomeServerName=/O=YourExchangeOrgName/OU=YourAdminGroupName
/cn=Configuration/cn=Servers/cn=YourExchangeServerName)(objectClass=User)

Hope this Helps.
