Rudy_Ooms_MVP thanks, Rudy. I'm setting them through Endpoint Security > Microsoft Defender Firewall rules.
I assigned a test rule this morning, it synced to the firewall then I removed it but it's still in the firewall.

So .... I guess ltsc 1903 isn't going to work- Found this because I ran into the same problem. The test machine is a Windows 11 23H2.

Changed the rule to allow and it did what it was supposed to.
Deleted the rule from Intune, it's still tattooed in the Defender firewall.
Possible something else changed? this is going to make it a bit more difficult to test rules before deploying them to production.
