In Unity connection 8.5, if message aging policy "" is set to N days, does it permanently delete the messages individually exactly N x 24 hours after the message was deleted or does Unity Connection run a purge of all messages past due to be deleted at a specific hour once a day (for example, at midnight).
In other words, if I have it set to 1 day and a message was "deleted" by a user at 1pm today, will Unity Connection purge such message at (1) 1pm tomorrow or (2) some scheduled time tomorrow after 1pm.
