Apps

Multi-Calendar Availability · hyc_appointment_multi_calendar · Odoo 19

Odoo Appointments only check a staff user's primary Google calendar, so meetings on other calendars (a second Google account, a shared client calendar, a subscribed Outlook feed) don't stop double-bookings. This module lets each appointment type pick the extra calendars whose busy times block its slots, via read-only Google Free/Busy. No two-way sync, no events copied, upgrade-safe.

Configure: open an appointment type, go to the Availability Calendars tab, click Refresh calendars from Google, and toggle which calendars should block.
