Shared mailboxes are treated as standard users, however they really should have a separate view. I would like to request that a new view is made avaiilable for Shared Mailboxes.
For the view the only thing that is interesting are the logon names (upn,samaccountname,name) and the exchange properties.
other things like employeeid, office location, data from HR systems, windows profile, etc are not really relevant.
