Summary: When uninstalling Exchange; you receive the following error message:
"One or more users currently use a mailbox store on this server"
This can occur for multiple reasons:
1. There was a user in which the mailbox was never created because it was not activated ie. user never logged in or no mail was sent to it.
2. There is a user who has Exchange attributes but no mailbox referencing this server.
Resolution:
1. Start ADUC; click find.
2. Click custom search in drop down
3. Click Advanced tab
4. In LDAP field type:
(msExchHomeServerName=/O=myexchangeorgname/
OU=myorgname/cn=Configuration/cn=Servers/cn=myexchangeserver)
(objectClass=User)
Substitue o=myexchangeorgname and OU=myorgname and cn=myexchangeserver with your values. To find these values you can open adsiedit and go to the properties of a user and find the msexchhomeservername property.
One thing to note; if the query comes back with no results; copy the query into notepad. Close out the ADUC search and re-open it and paste the search query. I've noticed that the query does not work when pasting even though you remove all spaces unless you restart ADUC search.
