  • Outdated Teams app: Bugs in older versions cause crashes.
  • Device overload: High CPU usage or insufficient RAM during calls.
  • Permissions & settings: Blocked mic/camera access or firewall interference.

Follow these proven steps in order. Most users resolve issues by step 3. Test a call after each one. πŸ‘

1️⃣ Quick Network Checks & Fixes

Start here – 70% of disconnects are network-related.

  1. Switch to wired Ethernet if on Wi-Fi.
  2. Run a speed test: Aim for 1.5 Mbps upload/download per participant (Microsoft bandwidth guide).
  3. Restart your router/modem. Disable VPN if active.
  4. Use Teams' network assessment tool: In Teams, go to Settings > Devices > Make a test call.

2️⃣ Update & Restart Teams App

Outdated apps are a frequent Teams call error source.

  • Desktop: Help > Check for updates. Restart Teams (quit fully via Task Manager).
  • Mobile/Web: Update via app store or browser refresh.
  • Clear cache: %appdata%\Microsoft\Teams on Windows – delete contents in subfolders, then relaunch.

3️⃣ Device & Permissions Reset

Platform Fix Steps
Windows 1. Settings > Privacy > Microphone/Camera > Allow Teams.
2. Run as admin: Right-click Teams icon.
3. Disable antivirus temporarily (e.g., Windows Defender real-time protection).

4️⃣ Advanced Fixes for Persistent Teams Disconnecting

If basics fail, level up:

  2. Reinstall Teams: Uninstall via Control Panel (Windows), then download fresh from official site.
  3. Hardware test: Use external mic/headset. Update audio drivers (Device Manager > Sound).
  4. Proxy/Firewall tweak: Ensure ports 80, 443, 3478-3481 UDP are open (Microsoft Teams ports doc).

5️⃣ When to Contact Support
