For Office 365, From_Email must be the same as the logon user. You are changing the From address, and that is not allowed.

Change your setting in mail.php file

'host' => env('MAIL_HOST', 'your-mail-host'),
  'from' => [
        'address' => env('MAIL_FROM_ADDRESS', '[email protected]'),
        'name' => env('MAIL_FROM_NAME', 'Your User Name'),
    ],
