Hi @IniobongNkanga-8038

To resolve the issue with Microsoft Teams proxy exemption, you can try the following methods:

• Bypass the proxy server: Microsoft recommends avoiding passing Teams traffic through a proxy server as much as possible, as this can cause latency and packet loss that can affect performance. You can configure firewall rules to allow Teams traffic to pass directly without going through the proxy server.
• Configure the firewall: Make sure the firewall allows all URLs and IP addresses required by Teams, including services such as Azure, Office 365, and Intune. You can refer to Microsoft's official documentation for a detailed list of URLs and IPs.
• Use a dedicated VLAN: Place Teams devices on a dedicated VLAN and provide them with direct internet access. This can help reduce potential issues with proxy servers.
• Disable SSL inspection: If you must use a proxy server, it is recommended to disable SSL inspection for the following URLs to reduce potential connection issues: *.media.azure.net *.bmc.cdn.office.net1
• Check proxy server settings: Make sure the proxy server does not require authentication, as many Teams devices (especially Android-based devices) do not support authenticated proxy servers.
