Mail Reader with OAuth2 Support for APP10

Hi @fahmy,

Since Microsoft are moving away from legacy authentication methods and Basic authentication will be deprecated, customers have to upgrade their Authentication method to OAuth2.

In the Microsoft documentation following is mentioned regarding the basic authentication disabling date. The basic authentication disabling is already in place since October 1, 2022 and only for Office 365 Operated by 21Vianet the disabling is happening on March 31, 2023.

--------------From MS Docuement ----------------------

Please refer to https://learn.microsoft.com/en-us/exchange/clients-and-mobile-in-exchange-online/deprecation-of-basic-authentication-exchange-online#pop-imap-and-smtp-auth

As a solution for this situation IFS has released a patch (165088, 165523) for this. But OAuth for the IFS mail reader is not supported with POP3 mail protocol (due to an incompatibility issue with Middleware Server) and only IMAP protocol is supported. Due to this limitation, after applying the above patches the user will have to move to the IMAP protocol if they are currently using POP3 protocol. These fixes enable the OAuth support for the IFS mail reader. 

After applying above fixes the following parameters are newly introduced for IFS mail reader.

• AUTH_METHOD
  Choose correct authentication method, Basic/ClientCredentials/AuthorizationCode. If ClientCredentials or AuthorizationCode is used, relevant permissions to read mails should be granted and configured for the user connecting to the mail server.
• CLIENT_ID
  OAuth Client Id of the application. This is required if ClientCredentials or AuthorizationCode auth method is used.
• CLIENT_SECRET
  OAuth Client Secret of the application. This is required if ClientCredentials or AuthorizationCode auth method is used.
• ACCESS_TOKEN
  Valid OAuth Access token which should be obtained with the permissions to read mails for the account which is configured according to the mail server setup for the user to authenticate the request. This is required if AuthorizationCode auth method is used.
• REFRESH_TOKEN
  Valid OAuth Refresh token obtained in the mail server setup which is used to get a new access token when the provided access token is expired. This is required if AuthorizationCode auth method is used.
• TOKEN_ENDPOINT
  Auth Token endpoint based on the mail server setup which is used to get the valid access token with permissions to read mails for the account which is configured. This is required if ClientCredentials or AuthorizationCode auth method is used.

The values for these parameters should be obtained from your mail server side.
