Re: Facts and figures or forced feeding
As a small business Office 365 subscriber, SkypefB stopped and Teams started one day a few weeks ago. I guess we knew it was coming in a general way, but still an inconvenience when it happened. SfB was OK more or less and we wouldn't have moved over by choice. The majority of our need is external communication, and Teams seems to be less easy to use and/or less functional for that.
It has prompted us to look at paid for alternatives again (another factor, most alternatives we've used from time to time seem to have much better sound & video quality than SfB or Teams), but I guess as Teams is in the O365 subscription, MS will always count us as users.
