Hello I want to federate teams with another domains. I'm following the next doc: https://docs.microsoft.com/es-es/microsoftteams/manage-external-access
but I don't understand this requirement.
To use the Teams client to communicate with an external user (whether that user is using Teams or Skype for Business), the Teams user must be homed in Skype for Business Online.
What does it mean? I don't have nothing withc skype
