The latest round of patches included a special little one (kb 943484). This patch limits the amount of information (64kb) returned from a query against a domain controller. It severely limits the usefullness of the Exchange Management console. In my particular case only 907 mailboxes are listed in Recipient Configuration/Mailbox view. In my opinion, this setting should be a configuration parameter for AD not hardcoded into an update. Kelly Goff
