Notes: 

• Service number is assigned to a resource group 
• The resource group is then assigned to the AA

Teams Devices

There are /very/ strict requirements around what conditional access and compliance policies you can configure when you have a teams hardware device such as a Yealink phone.

If you have any policies that implement a feature in the “not supported” list, you must go through and  exclude your teams devices from these. The recommended approach is device based filtering and excluding devices similar to

device.manufacturer -contains “yealink”

There is a semi reasonable blog/video on this below but it doesn’t cover all caveats and some of the intune configuration required.

This probably shouldn’t apply to your require MFA for admins conditional access policy.
