Connecting Outlook and Office 365 Calendars

If your team runs on Microsoft's ecosystem instead of Google's, you can connect Outlook or Office 365 calendars for the same two-way sync behavior — bookings flow out to Outlook, and events in Outlook block time on your booking page.

How the connection works

Once authorized, appointments booked through your calendar appear in the connected Outlook calendar automatically, and any event marked as busy in Outlook is read back in and blocks that time from being booked by a customer. This runs both directions continuously, not as a one-time import.

Setting it up

1. Go to your profile's Calendar Connections section.
2. Select Outlook or Office 365 and sign in through Microsoft's authorization screen.
3. Grant the requested calendar permissions in full — a limited or read-only grant will connect the account but won't support two-way sync.
4. Set the connected calendar as your linked calendar, and add any additional Outlook calendars you want treated as conflict calendars to block time without importing full details.

Per-user setup

Like other calendar integrations, this connection is tied to the individual user's profile, not shared across your whole team. Every staff member taking bookings on a shared or round-robin calendar needs to connect their own Outlook account, or their availability won't reflect what's actually on their calendar.

Good to know: Microsoft work/school accounts sometimes have admin-level restrictions on third-party app access — if authorization fails or permissions silently don't stick, that's usually an organization-level setting your IT admin controls, not something fixable from the calendar side alone.
