Sign in to Microsoft Teams. On the left side is a list of the different teams inside your organization.
Right-click the name of the team you want to add a guest to. In the menu that pops up, select Add Members.
Type the email address of the person you wish to add. If outside your organization, Teams will automatically add them as a guest.
Wait for the user to accept the access request, and they’ll be able to log in and use Teams just like a standard user.
