Microsoft Teams optimization refers to techniques and features designed to enhance the performance and user experience of Microsoft Teams, particularly in virtualized environments like Azure Virtual Desktop (AVD), Citrix, and VMware. The optimization aims to reduce resource usage, improve call quality, and ensure smooth operation, especially in scenarios where bandwidth or processing power might be limited.

1. In LEAF OS endpoints, including the EX500 thin client, Microsoft Teams optimization is supported in AVD, Windows 365, Microsoft RDS, Citrix, and VMware Horizon sessions.
2. For RX thin clients, specifically the RX420(RDP) and RX440(RDP) models, Microsoft Teams optimization is supported in AVD, Windows 365, and Microsoft RDS sessions starting from firmware version 4.9.100 and higher.
   

The following instructions summarize the necessary configurations to enable the Microsoft Teams optimization for AVD, Windows 365, and RDS sessions on LEAF OS endpoints, EX500, RX420(RDP), and RX440(RDP) thin clients.

Server-side configuration:

1. Refer to “UseMicrosoft Teams on AVD” document for the information.
   
2. For Microsoft Teams (audio/video) optimization in AVD, Windows 365, and RDP sessions, Remote Desktop WebRTC Redirector version 1.50 or higher must be used. The latest version can be found on the Microsoft website here. The WebRTC Redirector Service is a component that helps optimize the Microsoft Teams experience on Windows AVD and Windows 365.

Client-side configuration:

1. For AVD and Windows 365 connections: under General settings, select AVD Client operation mode, in AVD connection settings, select the Enable Microsoft Teams optimization checkbox.
   
2. For RDP connections: under General settings, select RDP Client operation mode, in RDP connection settings, choose AVD as Client type and select the Enable Microsoft Teams optimization checkbox.
