Step-by-Step Troubleshooting Microsoft Teams "Call Error" Disconnecting

Follow these prioritized steps. Most users fix it in under 10 minutes! 1️⃣ Start basic, escalate as needed.

1️⃣ Verify Network Basics

  1. Test internet speed: Aim for 1.5 Mbps upload/download per call. Use Speedtest.net.
  2. Switch to wired Ethernet if on Wi-Fi—it's rock-solid.

2️⃣ Update and Restart Teams

  • Check for updates: Click profile icon > Check for updates.
  • Clear cache: Windows: %appdata%\Microsoft\Teams → Delete contents. Restart app.
  • Full restart: Close Teams via Task Manager, relaunch.
