How to Fix "No Room License Found" and Add Yealink Devices in Microsoft Teams

Product: Microsoft Teams Rooms
Device & OS: not provided
Scenario: Setting up a Yealink conference system (MCore Pro and MTouch II) for Microsoft Teams meeting rooms.
Observed behavior: The system displays "No Room license found" and the device cannot be added in the Teams admin center because the Add device option is missing.

Before you start

Ensure you have global admin or Teams admin privileges in your Microsoft 365 tenant before attempting to purchase licenses or manage devices in the Teams admin center.

Solution 1Recommended

Purchase and Assign a Microsoft Teams Rooms License

Buy the appropriate Rooms license to activate your Yealink conference system and register it on your network.

Microsoft requires dedicated licenses for meeting room hardware. Standard user licenses will trigger a license error when applied to devices like the Yealink MCore Pro.

Purchase the license

Go to the Microsoft 365 admin center or contact your authorized Microsoft partner to purchase a Microsoft Teams Rooms license (Basic or Pro).

Assign the license

Navigate to the Users section in the admin center and assign the newly purchased Teams Rooms license to the resource account associated with your conference room.

Access Teams Rooms portal

Add the device

Click on Add device, enter the required Yealink device information (such as the MAC address), and click Save to register the device to your network.

Purchase and Assign a Microsoft Teams Rooms License

Missing Add Device Option: If you do not see the 'Add device' button, it may indicate insufficient admin permissions or a tenant configuration issue. Contact your Microsoft 365 administrator or Microsoft technical support for assistance.

Frequently Asked Questions

Why does my Yealink device say 'No Room license found'?

This error occurs because the Microsoft Teams Room resource account signed into the device (such as the MCore Pro) does not have an active Microsoft Teams Rooms Basic or Pro license assigned to it. Standard user licenses are no longer supported for meeting room devices.

What should I do if the 'Add device' button is missing in the Teams admin center?

The missing button is typically due to a lack of proper administrative roles or tenant provisioning delays. Ensure you are signed in as a Teams Administrator. If the issue persists across different browsers, contact Microsoft technical support or your licensing reseller.

Can I use a standard Microsoft 365 E3 or E5 license for a Teams Room device?

No. Microsoft updated its licensing requirements, meaning you must use a dedicated Microsoft Teams Rooms license (Basic or Pro) for dedicated meeting room devices like the Yealink MTouch II. Applying standard user licenses will result in a sign-in block or license error.
