Replacing basic auth for IMAP with OAuth 2.0 in an unattended application

Hey Shivian D,

I am by no means a developer but i have somewhat heard about the question you raised. Oauth 2.0 does support authentication against office 365 services without user intervention. To start off you will have to register the application in azure and retrieve a 'client id' and 'client secret' which you can later use in the code for obtaining a token. The following articles should help you get started (EWS) :

Thanks
