Azure AD Sync Project: Insufficient privileges to complete the operation

Hi All,

I am getting below error when adding user.

I have given all graph permissions as per document and also user is member of Global Administration role.

What could be the issue.

[System.Exception] [ServiceException]: Code: Authorization_RequestDenied - Message: Insufficient privileges to complete the operation.

[Microsoft.Graph.ServiceException] Code: Authorization_RequestDenied
Message: Insufficient privileges to complete the operation.

Inner error

Thank you in advance.

Kind Regards,

Dnyandev
