Recently we changed our Message Retention policy from "Keep all messages" to retain only the last 90 days. The process to purge messages runs nightly according to RC documentation. However, any messages created before the date of the policy change do not get removed.
I've opened a ticket with RC and the response is that only messages created AFTER the date of the policy change will be affected. In addition, I've been told by RC that they do not have a way to delete old messages but there "MAY" be a way for a site superadmin to delete messages.
I'm interested in removing messages older than 90 days and then let the message retention policy do the work going forward. Does anyone know how to delete old messages?
