Steps to identify the issue:
There is no auditing in the DLP Auditing table of a message sent that violates a DLP policy. Test with more than one rule to make sure the issue is not related to the rule
There are no records in the SIP filter logs for the messages sent
On the front end, run the following command via PowerShell:
“Get-CsServerApplication” - Returns information about the server applications in use in your organization
If the Lync_access_control “enabled” options are “false”. , that means the service isn’t registered.

Violate rules and see in the logs if the messages are shown.
Check if the DLP Blocks blocks or Replacing replaces the messages
