Hi Bambox, Can you please explain the situation in a bit more detail? are you saying that you have already rule configured to access Microsoft teams from your DMZ to INTERNET? are you configuring the rule with the application ID or based on the IP? if your receiving "Not Applicable" in your traffic logs, then you need to reverify the placement of your security rule, maybe move the rule to the top of the list and check. as per the Palo alto document Not-applicable means that the Palo Alto device has received data that will be discarded because the port or service that the traffic is coming in on is not allowed, or there is no rule or policy allowing that port or service. For example, if there was only one rule on the Palo Alto device and that rule allowed the application of web-browsing only on port/service 80, and traffic (web-browsing or any other application) is sent to the Palo Alto device on any other port/service besides 80, then the traffic is discarded or dropped and you'll see sessions with "not-applicable" in the application field.
