The Teams integration is, being polite, fragile. Its just not in any way fit for purpose if you want to use this to book meetings on your MS calendar. Relentlessly the Teams link isn't included in the bookings, and it loses the connection to Teams frequently. It has also shown times as available when they're not before. I wanted to like this product, but after battling with it feeling half-baked for ages, it might be time to move on.
