Good afternoon,
We have a very old version of Ensemble with one of our clients and they have no desire to upgrade anytime soon. We have gotten the all-clear to purge really old messages from the database, changing the days kept from 60 to 30. The option to Compact/Truncate is displayed in this version of Ensemble, but does not execute as it mentions not being actually present in this version.
There is an option in ^d DATABASE that restores unused space, however this does not return nearly as much free space as the refined Compact/Truncate procedure.
