I use garethp php-ews to connect EWS using oauth2.

I am receiving the access token but when passing it to the mail function (getMailItems,getMailbox,getFolder....etc) following fatal error with "UnauthorizedException" is showing.

Tried many ways but still the same.

`Fatal error: Uncaught garethp\ews\API\Exception\UnauthorizedException in C:\xampp\htdocs\exchange\vendor\garethp\php-ews\src\API\ExchangeWebServices.php:453 Stack trace: #0 C:\xampp\htdocs\exchange\vendor\garethp\php-ews\src\API\ExchangeWebServices.php(368): garethp\ews\API\ExchangeWebServices->handleNonSuccessfulResponses(NULL, 401)

Here are the parameters am passing :

$tokenEndpoint = 'https://login.microsoftonline.com/common/oauth2/v2.0/token';
 $authorizationEndpoint = 'https://login.microsoftonline.com/common/oauth2/v2.0/authorize';
 $clientId = '********';
 $clientSecret = '********';
 $redirectUri = 'http://localhost/testredirect.php';
 $scope = 'https://outlook.office.com/Mail.Read';

$token = ExchangeWebServicesAuth::getTokenFromAuthorizationCode($clientId, $clientSecret, $code, $redirectUri, $tokenEndpoint);
//Receiving the token correctly

$api = MailAPI::withCallbackToken('outlook.office365.com', $token);
// Here am getting the above mentioned exception. Tried with "$mail = $api->getMailItems();  $api->getFolderByDistinguishedId('inbox'); etc"
$mailbox = $api->getMailbox('inbox');
