Outlook Add-In | Graph API Configuration

Requirement: When user clicks on Custom Command Button send a Email.

Access Token: We are getting the Access Token using the below code.

Office.context.mailbox.getCallbackTokenAsync({ isRest: true }, function(result) {})

What we achieved: We are able to send a email from the Custom Command Button using the REST API https://outlook.office.com/api/v2.0/me/sendmail with the Access Token.

Problem with REST API: We came to know that Outlook Mail REST API is deprecated and will be out of service from November 2022

Replacement API/Service: As mentioned in the Outlook API Docs, We need to use the Graph API.

Problem with Replacement API/Service: As per the docs we need to setup SSO/OAuth for this API. But we don't want to do these things. We just want to keep the solution simple i.e when user clicks Custom Command Button send Email with any authentication process.

Question Is there any method/way we can directly call the Graph API using the Access Token without any SSO/OAuth/Azure setup? Currently we are receiving 401 Unauthorised Access error message.

Unfortunately, there's no way to call Microsoft Graph APIs using the token from Office.context.mailbox.getCallbackTokenAsync. That is probably why you received the 401 Unauthorised Access error.
