How to Sync Slack Status with Google Calendar
If you want to sync Slack status with Google Calendar, the quickest route is Slack's own Google Calendar app: connect it, open Settings on its Home tab, and turn on status sync. From then on, accepted meetings set your status to "In a meeting" and events titled OOO or PTO set "Out of office". That covers most people. It stops covering engineering teams the moment status starts doing a second job: telling colleagues who can be pulled into an incident right now.
