Hello Narender Singh Pawar,

Thank you for contacting Microsoft Support!

The “InvalidAuthenticationToken” error typically occurs when the access token used in your request is invalid or not properly configured. Here are some steps to help you resolve this issue:

1. Check Token Validity: Ensure that the access token is valid and not expired. You can use tools like JWT.io to decode and verify the token.
2. Correct Scopes: Make sure that the token includes the correct scopes for the permissions you have granted. For example, your token should include Files.Read.All and Files.ReadWrite.All.
3. Consent: Ensure that the necessary permissions have been consented to by an administrator if required.
4. Access Token in Header: Make sure that the access token is included in the HTTP Authorization header of your request as a Bearer token.

Please check documentation and follow the steps provided. Use Postman with the Microsoft Graph API

Hope this helps.

Hi @Narender Singh Pawar

I can reproduce your issue locally. This is because the target user lacks a valid MS 365 license. When you try to access MS 365 resources, an MS 365 license is necessary.

Please contact your administrator to assign an MS 365 license to the user and then try again.

Hope this helps.
