I'm running a pilot of Sensitivity Labels to replace Titus for Outlook 2016 by deploying the AIP UL client - we have Office 365/EMS+Security E3 licences.
Our corporate policy is to disallow any changes to label when replying or forwarding the email. So we don't allow downgrade even with a justification.
How can I get the same block on change for Sensitivity Labels? I tried removing the justification prompt, but that just removes the justification on change. Doh!
