Connect Microsoft Exchange with Cal ID
Fetch calendars from Microsoft Exchange via Exchange Web Services.
The Microsoft Exchange integration connects Microsoft Exchange with Cal ID so you can keep your calendar in sync with no manual work. It is built for anyone who lives in their calendar, from solo founders to whole sales and support teams. Once you link the two, every booking, reschedule, and cancellation flows through Microsoft Exchange automatically, and your Cal ID booking pages keep working exactly as before. It sets up in about a minute from the app directory and is free on every Cal ID plan, with no extra fees.
