We are currently experiencing an issue affecting email deliveries to Microsoft-hosted addresses (including Outlook.com, Hotmail.com, Live.com, and Office 365). Messages sent to these domains may be delayed or deferred. A small portion of emails may still be delivered, but most are impacted.
This appears to be due to a service disruption on Microsoft’s side. Our systems are operating normally, and we are monitoring the situation closely.
