Smart 1:1s are initially scheduled as a Free 🆓 event and will switch to Busy 🛡️ as your schedule changes to give maximum flexibility in your calendar while still ensuring that you get the time you need.
Smart 1:1s automatically flip to Busy 🛡️ :
24 hours ahead of their start time, and/or
when there is only one slot remaining for the Smart 1:1 within the same day.
This ensures a Smart 1:1 does not get reschedule unexpectedly due to an interruption.
A Smart 1:1 that has been locked can still be rescheduled. Refer to Reschedule a Smart 1:1.
