Cannot access onedrive details for another user

问题

While the endpoint works fine to get details of my own OneDrive I am having trouble using Microsoft Graph to get the status of another user's OneDrive. i.e. Do they have one, have they added any files.

First, I create a new user account.

Then, using Microsoft Graph Explorer I log in as myself, (an administrator) and I request:

https://graph.microsoft.com/v1.0/users/{user-id}/drive

This returns

{
"error": {
    "code": "ResourceNotFound",
    "message": "User's mysite not found.",
    "innerError": {
        "request-id": "6c2f1d09-ebb1-49fe-83ac-46caf946eefa",
        "date": "2017-11-02T17:55:45"
    }
}

}

If I then log in as the user and access her OneDrive via the web and retry the same endpoint it returns:

{
"error": {
    "code": "itemNotFound",
    "message": "The resource could not be found.",
    "innerError": {
        "request-id": "aecda4bb-4baf-42ab-81f0-ce9e3b959dd8",
        "date": "2017-11-02T17:59:41"
    }
}

}

Shouldn't it return the id of the drive here instead? I am requesting all permissions when signing in via Microsoft Graph Explorer.

Thanks for your help!
