November 4, 2018 - Still a problem. It's pretty obvious Transport Rules are not applied before DLP rules like the documentation says here - https://docs.microsoft.com/en-us/office365/securitycompliance/how-dlp-works-between-admin-centers#how-dlp-in-the-security--compliance-center-works-with-dlp-and-transport-rules-in-the-exchange-admin-center.
Considering this has been a problem for at least over a year... I wonder if Microsoft reads this stuff.
I guess I'll save my typing. What a cluster-fsck.
