Microsoft Teams is a collaboration platform that allows users to conduct online meetings easily. To use it, first open the Teams app or access it via a browser, then sign in with your work or school email. Meetings can be joined through an email invitation link or directly from the Teams Calendar by clicking the "Join" button. Before entering the meeting, you'll see a preview screen where you can turn your microphone or camera on/off and select your audio device. During the meeting, you can use features like mute/unmute, turn video on/off, chat, raise hand, share screen, and view participants. To share your screen, click the Share icon and select a window or presentation. You can also record the meeting if permitted. Always mute yourself when not speaking to avoid background noise. After the meeting, all chat messages, shared files, and recordings (if any) remain accessible in the Teams chat. Use a stable internet connection and a headset for the best experience, and remember to leave the meeting by clicking the red "Leave" button once it's over.
