Exchange 2003 Auto Accept Agent vs. direct booking

Robert, good question. The recommendation is to use the Exchange Mailbox Manager to automatically purge the AAA managed mailboxes.  The mailbox manager runs on designated servers and purges mailboxes based on recipient policies.  This allows the Exchange administrator to select the exact mailboxes that will be examined and which messages (by age and size) that will be purged. The recommended recipient policy should select only the mailboxes that are being processed by the Auto Accept Agent.  The filter for the Mailbox Manager recipient policy will query by Alias and Information Store database.  Since the AAA managed conference rooms will generally be consolidated onto the same database, this is a reliable method of scoping the filter to the right mailboxes.  Since there is no need to set any special AD attributes, the amount of administrative overhead is kept to a minimum.  The one draw back is that any mailbox that ceases to be AAA managed will continue to be affected by Mailbox Manager until it is moved to a different database. The one short-coming of the mailbox manager is that it does not purge recurring appointments.  This is an explicit part of the design to avoid premature deletion of still active recurring meetings. You will have to do it manually.To stop the AAA from processing meeting request for a specific mailbox, unregister the sink from the mailbox. The REGISTERMAILBOX.VBS script includes an uninstall option (/U) to perform this task.REGISTERMAILBOX.VBS must be run from the console of the Exchange server. There isn’t a remote administration option with this script.
