My users used to be able to run a manual compact on their mail files to recover space.  After moving to transaction logging on my 8.5.1 server they can no longer run this themselves.  I was wondering if you could make an action to "Recover unused space" on their mail file.  This way they can run an action that would essential allow them to run a compact -B.
 
This would save them from having to contact me to do it for them at the administration console.
Thanks for considering this.
