Allow guests to change avatar and description
It doesn't seem like a guests can change their avatar or information such as job title or location. When you have a lot of guests in your team having a picture and job title would be very useful.
when i add a team member using their email address, that email becomes the "visible username" ... this forces me to memorize who each person is ... please allow us to rename the username to a more customizable name ...
Seems like they can't even see avatars https://microsoftteams.uservoice.com/forums/555103-public/suggestions/35537563-allow-guests-to-see-avatars
