Thanks. That helps a lot!

I was aware of the file sharing part. I didn't know you had to invite a person to videochat with him, since we would just call each other up.


As far as I understand it, you can not just call a guest user up (and vica versa)... they need to be invited to a meeting and it needs to be initiated by the person with the licensed office 365 account?
