How to copy free/busy times out of Outlook as text
Outlook displays free/busy in a dozen places — the calendar grid, Scheduling Assistant, people cards — and exports it in exactly zero of them. There is no "copy my open times" button. If you've searched for one, this page is the answer to why you couldn't find it, and what to use instead.
What people try first
Screenshotting the calendar (unreadable on phones, leaks meeting details), forwarding the calendar itself (overshares everything), or the classic: reading the week view and typing. Microsoft's own "share calendar availability" features are built around granting access, not producing text.
Free/busy to clipboard
OpenSlot exists precisely for this gap. It authenticates with your Microsoft 365 account, reads free/busy (read-only — it never sees meeting titles or details, and stores nothing), inverts it into free slots inside your working hours, and formats the result as text:
All times in US/Eastern • Today 07/08 03:30 PM - 04:00 PM 05:00 PM - 05:30 PM • Thursday 07/09 09:30 AM - 10:30 AM 12:00 PM - 01:00 PM 02:30 PM - 03:00 PM
One button copies it; another downloads a .txt. It works for your own calendar, for colleagues, or for the merged intersection of a whole group — which turns the unanswerable "when are all four of us free in the next month?" into the same single click.
Skip the retyping
OpenSlot reads Outlook free/busy and hands you the merged, paste-ready list — any people, any timezone, up to 60 days out. Free to start.
