Yup, it does exactly what I want it to do: link scheduled meetings to my Outlook calendar (corp requirement) and let me join from a notification box. We have Slack for everything else.

It’s not great, but it’s certainly okay. Call quality is fine, the chat is crappy but gets the job done (supports links, files, and plain text, which is enough), and audio/camera settings are surprisingly decent. It works well for our use-case, which is scheduled meetings. Impromptu (i.e. useful) meetings happen over Slack.
