MS ToDo API is giving error for few users in Taskfolders Endpoint

Question

MS ToDo API is giving error for few users when using following endpoint :

https://outlook.office.com/api/v2.0/me/taskfolders

Here is the piece of code :

$accessToken = "eyJ0eXAiOiJKV1QiLCJub25jZSI6I*******sYVg0X0";
$url = "https://outlook.office.com/api/v2.0/me/taskfolders";
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);
curl_setopt_array($ch, array(
    CURLOPT_HTTPHEADER  => array('Authorization: Bearer '.$accessToken)
));
$output=curl_exec($ch);

Here is the error which I am getting :

stdClass Object (
[error] => stdClass Object
    (
        [code] => ErrorItemNotFound
        [message] => The specified object was not found in the store.
    )

 )

As per the documentation of MS, we should get the list of default folder.

Here is the MS documentation link

That means, I should get default folder list in response and which I am getting in case of other users. I checked the token validity, it is alive.

Any help is appreciated and thank you in advance.

In case if you're talking about shared tasks then it's not supported at this point. I remember an user voice on this - https://microsoftgraph.uservoice.com/forums/920506-microsoft-graph-feature-requests/suggestions/40295248-get-shared-task-folders-using-graph-api. You may want to vote for it, so that Microsoft can consider for it
