Getting Access Denied even though I have the proper access token and permissions

Question

Hi,

So my main goal is to get the list of emails from my outlook thru automation.

My steps to reproduce:

• Get access token from https://login.microsoftonline.com/consumers/oauth2/v2.0/token
• Use access token to get User ID from https://graph.microsoft.com/v1.0/me
• Use access token again to perform GET request on https://graph.microsoft.com/v1.0/users/${userId}/messages

The response I get is:

error: {

code: 'ErrorAccessDenied',

message: 'Access is denied. Check credentials and try again.'

}

But I know the access token has got to be valid since I'm able to hit the graph API and get my user info (e.g. mail, displayName, givenName, etc).

The permissions on my App:

Any insight would be well appreciated.

Hi @josh j

Try logging into your MS Entra ID as a global admin, then find the calling app and grant admin consent for the above permissions.

Hope this helps.
