Solution 1Recommended

Consult Microsoft Support and Defender Communities

Because this involves complex Azure Virtual Desktop multi-session routing and backend licensing calculations, consulting official Microsoft experts is the recommended path for resolution.

In multi-session environments, licensing systems can sometimes miscalculate concurrent user connections as separate endpoint instances. Resolving this requires backend checks or specific architectural adjustments recommended by Microsoft engineers.

1
Check Microsoft Defender for Cloud Q&A

Navigate to the official Microsoft Q&A portal (learn.microsoft.com/en-us/answers) and search or post your question using the 'defender-for-cloud' tag to get insights from licensing experts.

2
Visit the Tech Community

Go to the Microsoft Tech Community for Defender for Endpoint and detail your specific Azure Virtual Desktop multi-session topology to see how other enterprise administrators handle license tracking.

3
Open a Support Ticket

Log into the Microsoft 365 admin center, navigate to 'Support' on the left sidebar, select 'New service request', and describe your license overuse issue with Azure Virtual Desktop for direct assistance.

Consult Microsoft Support and Defender Communities
Gather Deployment Details: Before opening a ticket, have your Azure subscription ID, the number of AVD host pools, and details about your onboarding scripts ready for the support team.
