Answer 1

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

Answer 2

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'),
    ],

Answer 3

I was using this to test:

Mail::send('welcome',[],function($message){ $message->to('[email protected]')->subject('laravel mail'); });

This code made this error

Swift_TransportException with message 'Expected response code 250 but got code "554"

I added a from clause that matched my config in .env

Mail::send('welcome',[],function($message){ $message->from('[email protected]')->to('[email protected]')->subject('laravel mail'); });

I got the email.
