Share files / message those not in your organization
1. Let users share files and message with Skype for business users who are not in their organization.
2 Let users migrate back to Skype for Business.
Teams is useless for me without 1. And it does not seem possible to delete and migrate back. Several of our company's processes are not working as we collaborate regularly with people who are not in our organization. We are currently looking for a replacement, since Teams has lost functionality that Skype for Business had.
