Was hoping that Groups would help me organize a team of internal and externals (Guests) But reviewing the recently released documentation, I wonder if too many features are disabled for practical use. Specifically - Will any of the disable social features (like, @mention) follow in the future? - Unable to view group calendar - could the calendar be published using a different mechanism? - View and edit group files - if this is only by link or attachment, then will guests not be able to browse the files they have access to? It seems like embedded files in the shared OneNote would still be an easier approach to content sharing. - Assume we can edit the welcome email template (logo, text) but that is not mentioned in the documentation. Is there another mechanism that might work better?
