Outlook Calendar
The other half of the calendar world, on Microsoft 365.
What it does
Completes calendar coverage for the SMB half that lives in Microsoft 365 rather than Google Workspace. Same reminder and booking flows.
Connecting it
Microsoft OAuth with delegated `Calendars.ReadWrite` — which needs no admin consent, so an owner on Microsoft 365 Business can authorise it themselves.
What to know before you rely on it
- Polled, not pushed, and deliberately
- Microsoft’s change notifications for calendar data expire in under a day when they carry the data itself. A renewal daemon that misses a window silently stops a customer’s reminders, so the connector reads the calendar view twice a day and again 90 minutes out.
- An IT department can still say no
- Consent can be disabled org-wide by an administrator. When that happens the connector produces the admin-consent URL to forward, rather than an error nobody can act on.
