Fix Teams Call Drops During Video in Microsoft Edge

Your Teams video calls keep dropping when you use Microsoft Edge. The call freezes, the audio cuts, or the meeting ends abruptly. This usually happens because Edge blocks the video stream or because Teams cannot access the camera and microphone. In this article, you will learn the exact settings to change in Edge and Teams to stop the drops.

Why Teams Calls Drop During Video in Edge

Teams relies on your browser to stream video and audio. Edge has several features that can interfere with this stream. The most common cause is a permission setting that blocks the camera or microphone after a few minutes. Edge may also use hardware acceleration, which can cause the video decoder to crash if your graphics driver is outdated. Another cause is that Edge’s sleeping tabs feature pauses the Teams tab when you switch to another tab, which disconnects the call.

When the video stream is interrupted, Teams cannot maintain the connection. The server sees no incoming data and ends the call. This is why the call drops completely instead of just showing a frozen image.

Edge Permissions and Hardware Acceleration

Edge asks for permission to use the camera and microphone the first time you join a Teams meeting. If you clicked “Block” or if the permission expired, Edge will not send video. Hardware acceleration offloads video decoding to your GPU. If your GPU driver is not compatible with Edge, the video can crash, causing the call to drop.

Sleeping Tabs and Background Throttling

Edge has a feature that puts inactive tabs to sleep to save resources. When you switch to another tab during a Teams call, Edge may sleep the Teams tab. This stops the video and audio transmission, and Teams drops the call. Background throttling also reduces the CPU usage of tabs that are not visible, which can interrupt the video stream.

Steps to Fix Teams Call Drops in Edge

Follow these steps in order. Each step addresses a specific cause. After each step, test a video call to see if the issue is resolved.

Step 1: Allow Camera and Microphone Permissions in Edge

1. Open Edge settings
   Click the three-dot menu in the top-right corner of Edge, then select “Settings”.
2. Go to site permissions
   In the left sidebar, click “Cookies and site permissions”. Scroll down and click “Camera” and then “Microphone”.
3. Allow Teams domains
   Under “Allow”, check that “teams.microsoft.com” and “teams.live.com” are listed. If not, click “Add” and enter each domain. Set the toggle to “Ask before accessing” or “Allow”.
4. Reload Teams
   Close the Teams tab and open it again. Join a test call to confirm the camera and microphone work.

Step 2: Disable Hardware Acceleration in Edge

1. Open Edge settings
   Go to Edge > Settings > System and performance.
2. Turn off hardware acceleration
   Find “Use hardware acceleration when available” and toggle it off.
3. Restart Edge
   Click “Restart” in the pop-up that appears. Then open Teams and test a video call.

Step 3: Disable Sleeping Tabs and Background Throttling

1. Open Edge performance settings
   Go to Edge > Settings > System and performance.
2. Turn off sleeping tabs
   Toggle off “Save resources with sleeping tabs”. If you want to keep it on, click “Sleeping tabs” and add “teams.microsoft.com” to the “Never sleep these sites” list.
3. Disable background throttling
   Toggle off “Efficiency mode” and “Startup boost” if they are on. These can also throttle the Teams tab.
4. Restart Edge
   Close all Edge windows and reopen them. Test Teams again.

Step 4: Check Teams Device Settings

1. Open Teams settings
   In Teams, click your profile picture at the top-right, then select “Settings”.
2. Go to Devices
   Click “Devices” in the left menu. Under “Camera”, select the correct webcam. Under “Microphone”, select the correct mic. Under “Speaker”, select your output device.
3. Test the devices
   Click “Make a test call” and follow the prompts. This verifies that Teams can access your hardware.

Step 5: Clear Edge Cache and Cookies for Teams

1. Open Edge history
   Click the three-dot menu, then “History”, then “Clear browsing data”.
2. Select cached data
   Check “Cached images and files” and “Cookies and other site data”. Uncheck everything else to avoid losing passwords.
3. Clear the data
   Click “Clear now”. Then reload Teams and sign in again. Test a video call.

Step 6: Update Edge and Your Graphics Driver

1. Update Edge
   Go to Edge > Settings > About Microsoft Edge. Edge will check for updates and install them automatically. Restart Edge after updating.
2. Update your graphics driver
   Press Windows key + X, then click “Device Manager”. Expand “Display adapters”, right-click your GPU, and select “Update driver”. Choose “Search automatically for drivers”.
3. Restart your computer
   After updating, restart Windows. Then test Teams again.

If Teams Still Drops Calls in Edge

Sometimes the issue is not in Edge but in the network or in Teams itself. Try these additional checks.

Teams Shows “Network Connection Lost” Before the Drop

This means your internet connection is unstable. Use a wired Ethernet connection instead of Wi-Fi. Close other apps that use bandwidth, such as streaming services or large downloads. You can also run the Teams network diagnostic tool by going to Teams > Settings > General and clicking “Network diagnostic”.

Teams Call Drops Only When You Share Your Screen

Screen sharing uses extra bandwidth. In Edge, go to Settings > System and performance and turn off “Use graphics acceleration when available”. Also lower the video quality in Teams by going to Settings > Devices and turning off “High-fidelity music mode”.

Teams Call Drops on a Specific Network

Your firewall or proxy may block Teams traffic. Check with your IT department. They can allow the Teams domains and ports listed in the Microsoft 365 documentation. You can also try using Teams on your phone’s hotspot to see if the issue is network-specific.

Teams Call Drops When You Switch Tabs

This is caused by sleeping tabs. Follow Step 3 above. If you already disabled sleeping tabs, check that Edge’s “Efficiency mode” is off. Also, keep the Teams tab in the foreground during important calls.

Edge Settings vs Teams Settings: What Fixes Each Drop Cause

Item	Edge Setting	Teams Setting
Camera access	Settings > Cookies and site permissions > Camera	Settings > Devices > Camera
Microphone access	Settings > Cookies and site permissions > Microphone	Settings > Devices > Microphone
Video crashes	Settings > System and performance > Use hardware acceleration when available	Settings > Devices > Disable high-fidelity music mode
Tab goes to sleep	Settings > System and performance > Sleeping tabs	None
Network drops	None	Settings > General > Network diagnostic

You can now stop Teams video call drops in Edge by adjusting permissions, disabling hardware acceleration, and turning off sleeping tabs. Start with the permission check because it is the most common cause. Then test each fix with a short video call. For persistent drops, update your graphics driver and run the Teams network diagnostic. Use a wired connection for critical meetings to eliminate network issues.
