Turn Outlook calendars into paste-ready availability lists
About OpenSlot
Booking links make people schedule for you. OpenSlot hands them your free times instead. Pick people, a timezone and a window; it reads Microsoft 365 free/busy (read-only, nothing stored) and returns one clean, paste-ready list of every slot everyone is free. Works on the web and inside Outlook: insert into the email you're writing, or open it on a received message and hit Reply with times. Working hours, minimum slot and weekends are remembered. Free plan, 14-day Pro trial, no card.
