Explain the process of setting up OAuth authentication for accessing Outlook data programmatically.

OAuth authentication allows third-party applications to access user data without exposing user credentials. When setting up OAuth for accessing Outlook data programmatically :

* Register the Application : Register your application with the Microsoft identity platform to obtain the client ID and client secret.

* Configure Redirect URI : Set up a redirect URI in the Azure portal.

* Request Authorization Code : Direct the user to the Microsoft authorization endpoint to obtain an authorization code.

* Exchange Authorization Code for Tokens : Use the authorization code to request access and refresh tokens.

* Access Outlook Data : Use the access token to make API requests to access Outlook data.

* Handle Token Refresh : Implement logic to refresh the access token using the refresh token.
