Just read through the Teams roadmap and it's insane to me that this issue has been going on so long and doesn't get priority. Pretty much any business previously using Skype has external contacts and they're by their nature...external. They can't be compelled to migrate to Teams.
It really doesn't matter how good Teams is in any other regard until this is solved because the only choice it now offers is between using Teams AND Skype or Skype alone.
We need full interoperability between Teams and Skype (and Skype for Business), meaning group chats, screenshare, group calls, adding by Skype ID, merging contacts.
It's also maddening because it makes zero business sense. Network effect will be the biggest predictor of success and legacy Skype use is the one massive advantage MS have. They paid $8.5B to get it but are not using it. Really they should push everything else on the roadmap and muster their entire development effort around delivering this as first priority.
