UnauthorizedException when connecting to exchange accounts using oauth2 - garethp - php-ews

[ashwindas77]

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) #1 C:\xampp\htdocs\exchange\vendor\garethp\php-ews\src\API\ExchangeWebServices.php(301): garethp\ews\API\ExchangeWebServices->processResponse(NULL) #2 C:\xampp\htdocs\exchange\vendor\garethp\php-ews\src\API.php(362): garethp\ews\API\ExchangeWebServices->__call('GetFolder', Array) #3 C:\xampp\htdocs\exchange\vendor\garethp\php-ews\src\API.php(378): garethp\ews\API->getFolder(Array) #4 C:\xampp\htdocs\exchange\vendor\garethp\php-ews\src\Mail\MailAPI.php(22): garethp\ews\API->getFolderByDistinguishedId('inbox') #5 C:\xampp\htdocs\exchange\vendor\garethp\php-ews\src\Mail\MailAPI.php(81): garethp\ews\Mail\MailAPI->getFolderId() #6 C:\xampp\htdocs\exchange\testSync.php(50): garethp\ews\Mail\MailAPI in C:\xampp\htdocs\exchange\vendor\garethp\php-ews\src\API\ExchangeWebServices.php on line 453

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');
