Office 365 received the message that you specified. Unfortunately, we haven't been able to deliver it to the recipient ({0}) yet. Office 365 can't connect to your organization's mail server because we can't get its DNS record. This is either due to a typo in your Office 365 connector configuration or a problem with the way your organization's domain is set upon your domain�s host provider website.
