If you don't have an Office 365 account, you can join our Skype for Business meetings as a guest through your Web Browser by installing the Web App plugin. This guide will show you the steps you need to take to do this. Please note that you will need to have Administrator rights on your PC to perform these steps. You will also need a microphone and speakers (preferably earphones) to join an online meeting. We also like you to have a webcam so that we can see you.
