Cast content to a Microsoft Teams Room
You can cast content from your computer to a Microsoft Teams Room (MTR) or a Surface Hub device. This includes screens, windows, and PowerPoint live. You can choose to Just cast or Cast and join meetings that are scheduled on your calendar. Additional attendees can be added through the desktop app or by using the MTR device console.
Before you beginÂ
-
Ensure you have access to MTR on Windows, MTR on Android, or Surface Hub devices.
-
Enable the Bluetooth beaconing setting on your Teams devices.
-
Enable Automatically accept proximity-based meeting invitations setting on the Teams device for best results.
-
Your account must be signed into an account that's in the same tenant as the Teams device you want to cast to. If accounts are on different tenants, the tenants must be federated.
Note: Automatically accept proximity-based meeting invitations will only function when a wireless icon is present next to the room name.
