Announcing OAuth 2.0 Client Credentials Flow support for POP and IMAP protocols in Exchange Online

Hi All,

Anyone knows of C# implementation example for the POP connection using OAUTH 2 with Client Credentials? I have got the ClientId, TenantId and Client Secrat.

In Postman:

https://login.microsoftonline.com/{tenantId}/oauth2/v2.0/token 

returns the access_token for the provided:

client_id : {clientId}

grant_type : client_credentials

scope: https://ps.outlook.com/.default

client_secret: {client secret's Value created in Azure, for the registered application}

but, is there an example to do this in C# backend process and further creating the POP connect to use the access token and download mails?

MailKit/ MimeKit seems to be providing the POPClient implementation that allows XAUTH2 authentication type, But it there an implementation that does not require the use of third party POP client?

Regards,

A
