+1 for MS Teams. I am forced to use it at work, too.

Terrible audio focus on a single speaker, it really forces you to speak like on these old CB radios where you had to say "over" every time you were done talking.

The single window UI follows the mobile-first trend but is awfully inefficient on my three monitor setup, even more so with screen sharing.

Plus, our admins lock the whole MS Office 365 down so that there are no APIs or third-party plugins allowed. Data in it is just trapped.

Such a waste of human potential.
