How does Cronofy connect to Exchange servers?
Cronofy uses the Exchange Web Services API to interact with end-user’s Exchange servers.
This means that our services need HTTPS (TCP, port 443)
access to the Exchange Services API endpoint. It generally looks something like this example:
https://webmail.mycompany.com/EWS/Exchange.asmx
If your organization has implemented AutoDiscovery our service will be able to automatically detect this.
