Using Outlook.com with a custom domain I am noticing that inbound email is delayed resulting in people emailing me receiving a delivery status notification:

This is an automatically generated Delivery Status Notification.

THIS IS A WARNING MESSAGE ONLY.

YOU DO NOT NEED TO RESEND YOUR MESSAGE.

Delivery to the following recipients has been delayed.

The service status page, however, shows everything is operating normally.  For Outlook.com is phone support availble to further diagnose the issue?  I understand it is a free service, but I want to ensure the operations team is aware of the issue and what the expected time to repair is.
