Calendar connection
The Calendar section connects the mailbox that owns this page's events and reads the team's availability. A dedicated mailbox such as bookings@yourdomain is recommended.
Click Connect Microsoft 365 or Connect Google Calendar and sign in with that mailbox. Only calendar access is requested, never mail, contacts or files. The status badge then reads Connected and healthy, or explains what needs attention, such as Consent required or Credential expiring. Verify read and Verify read + write test the connection; the write test creates and removes a test event.
Calendars. After connecting, click Refresh list, tick the calendars whose events should block availability, and choose the one that receives bookings. Save calendars.
Without a connection, availability comes from your rules and existing bookings only, and no calendar events or Teams links are created.
