Exchange Server does not support OAuth. Instead, the user is prompted during the authentication flow for the Exchange Server server URL, username, and password, which will be used to authenticate requests. Passwords and secret keys are encrypted and stored securely.
You can test this via the Kloudless API Explorer.
