To true. We use MSTeams for work. The issue isn't the portal, it's the volume and length of meetings. Most of these could be deferred to the Forum function, email, Yammer, OneNote; even a good old-fashioned audio-only conversation. We recently introduced a drive to reduce meetings to 45/50mins with a short break halfway through, purely to stop people booking your calendar with back-to-back 1 hour (or much longer) sessions. The campaign continues!
