Knowing who is online/available at a glance.
I can't see the status of all our users at one time in Teams. Skype was a management tool you took away without warning, replacing it with a tool that does not offer the same functionality. I am a small business owner, happy with the functionality we had.Why couldn't Microsoft anticipate a need for this feature (aren't all the features of their software documented?) and make sure it was in Teams before they forced us to switch? Why does Microsoft constantly force their users to do whatever they want, rather than allowing the users to do what they want? It's infuriating, wastes our time, and makes us realize that Microsoft solutions are unreliable and dangerous for businesses that do not have the resources to stay informed and prepare for all the changes that Microsoft is constantly deploying.
