OnceHub communicates with your Exchange/Outlook Calendar in real time using an encrypted Exchange Web Services (EWS) connection, a well-established official Microsoft protocol. All credentials and data traffic are fully encrypted.
What does Exchange integration mean?
Exchange is a server that manages mailboxes, contacts, calendars and more. Exchange users never access Exchange directly, but rather through an email client. This can be an Outlook client on a PC or Mac, a mobile device, or web access via the browser. OnceHub integrates directly with Exchange while you keep using whichever calendar access method you're currently using.
