Email Sending Microsoft Outlook Outage

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.

Details for Outlook outage: https://status.cloud.microsoft/m365/

Microsoft has resolved the issue and we have confirmed that the service has back to normal.

Yahoo has deferred the emails we sent them in the last 24 hours. This means emails to Yahoo & AOL addresses will be delayed or deferred.

We apologize for the inconvenience and are actively working to resolve this issue.

The Yahoo deferral issue has been fixed. Our engineers are currently monitoring the situation.
