🛠️ Step-by-Step Fixes for Microsoft Teams "Test Call" Error 2026

Start with the simplest solutions first – they resolve 80% of cases. We'll build from basic to advanced, so stick around for the full wins.

1. 1️⃣ Verify Microphone Permissions
   Teams needs full mic access. Right-click the Teams icon in your taskbar > Settings > Privacy & security > Microphone. Ensure "Allow apps to access your microphone" is ON, and Teams is listed with access granted. Test again – boom, fixed for many!
