I am unable to participate in Microsoft Teams sessions conducted by business colleagues. When I tried to set up Microsoft Teams on my iPhone and my Microsoft computer in both cases I received the message "[my email] hasn't been added to your organization directory. Contact you administrator or try a different email. I only have one email. I am an independent consultant and not part of large organization with a dedicated "administrator." I am not computer savvy and have no idea what to do. I called Microself help and the tech referred me to the Microsoft "tech community" site.
