    I have a single Exchange 2003 Server(On Windows Server 2003) I need to decommission.

    As I uninstall Exchange I get the error message "The component"Microsoft Exchange Messaging and Collaboration Services" cannot be assigned the action " Remove" because: -One or more users currently use a mailbox store on this server. These users must be moved to a mailbox store on a different server or be mail disabled before uninstalling.

    The only mailboxes left are systemattendant's so why am I getting this message.  Should I delete this mailbox in order to complete the uninstall?

    When decommissioning what other tasks do I need to complete?

    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.
