FAQs

My microphone isn't working in Microsoft Teams on my Mac. What should I do?
First, ensure your microphone is selected as the input device in Teams settings. Check your Mac's system preferences to confirm the microphone is working correctly. Try restarting Teams, your Mac, or testing with a different microphone. If the issue persists, check for driver updates or conflicts with other audio applications.
My video is blurry or pixelated in Microsoft Teams. How can I fix this?
Try adjusting your camera's resolution in Teams settings. Ensure sufficient bandwidth by closing unnecessary applications. Check your internet connection speed. If using an external webcam, test with a different one. Consider upgrading your internet plan if bandwidth is consistently low.
I'm experiencing echo or feedback during my Teams calls. What's causing this?
Echo often stems from having multiple audio input devices active or from the microphone picking up the speaker's output. Mute your microphone when not speaking. Check your audio settings to ensure only one input device is selected. If using headphones, ensure they are correctly plugged in and not amplifying the speaker output. Adjust the microphone's proximity to reduce audio feedback.
