Improve Teams to Skype for Business Interoperability
I realize Skype for Business is planning on being deprecated. While this is fine on paper, the reality is many companies will continue to use SfB and even Lync on-premise, so the Interoperability between Teams and SfB needs to be improved, or there will be issues. Currently, we are not able to send files or screen-share between the two clients, and those alone would be deal-breakers for companies that aren't switching to Teams anytime soon.

What a great Idea, we really need this before we can switch to teams, we communicate with many external customers that do not have Teams yet.
