Does PrinterOn Enterprise support OAuth authentication to Exchange Web Services? - c07721400

OAuth Configuration for using EWS with modern authentication was introduced in version 4.2.0 released in November 2018.

Required information for using EWS (Exchange Web Services) for basic authentication:

Service URL: The URL depends on which service you’re using. For Office 365 mail services, the URL is always as following: https://outlook.office365.com/EWS/Exchange.asmx

Mailbox Username: The email address dedicated for PrinterOn mailbox. For example, printeron@xyz-company.com.

Mailbox Password: The password used to connect to the EWS server and monitor the incoming mailbox. The password for the above email address.

Enable OAuth: This option enables modern authentication / OAuth V2

Authority: The location from which the EWS service requests Access, ID, and Refresh tokens, which the service uses to determine the authentication status of the user. Enter the value https://login.windows.net/{tenant}.onmicrosoft.com. For example, https://login.windows.net/printeron.onmicrosoft.com.

Client ID: The unique ID of your EWS app registration, generated by Azure AD. For example. 92e40241-d684-443a-9a12-690a2769156d.

Server Name: The resource server name. https://outlook.office365.com.

Additional steps that are required are within Azure:

If you are enabling OAuth authentication for your EWS service, you must register your EWS service with Azure AD and define the level of access to the EWS service the user has once authenticated.
