Can you add a toggle button in the UI to make it easy to switch between work and personal?
Make it easy on the user interface to toggle between work and personal teams. Done in the right way will help drive adoption of Teams for Personal use and not just work use.
We also have this problem in business life: freelancers are often belong to teams in different companies. If we integrate them (or customer employees) in our project-teams they have to be „connected“ to our teams environment. But if they in our environment they miss all news and calls from their other teams … annoying! Why don’t you solve it like an e-mail account in outlook? Several accounts in the same App – working and being active at the same time.
