title: Laravel sending email with Office 365 Email
body: <p>We've changed from gmail to office 365, but the issue: <code>Client does not have permissions to send as this sender</code> 550 when sending email.</p>
  
  <p>Do we have any configuration in office 365 mail service to enable sending email from website/application?</p>
  
  <p>This is my <code>.env</code> configuration:</p>
  
  <pre><code>MAIL_DRIVER=smtp
  MAIL_HOST=smtp.office365.com
  MAIL_PORT=587
  MAIL_USERNAME=mail_username
  MAIL_PASSWORD=mail_password
  MAIL_ENCRYPTION=tls
  </code></pre>
