Updates

  1. Monitoring

    Microsoft’s incident is ongoing, and they haven’t yet given an estimate for full recovery. We’re continuing to retry emails to Microsoft-hosted addresses that show a “Delivery Delayed” status. There’s no need to retry these. If Microsoft’s outage continues past our retry window, some of these emails may bounce. You’ll receive a bounce event for each one, and you can retry those emails once Microsoft recovers.

  2. Monitoring

    Microsoft is still working to resolve the incident affecting email delivery to Microsoft 365. Emails to Microsoft-hosted addresses may continue to show a “Delivery Delayed” status. There’s no need to retry them: we’re retrying automatically, and they’ll be delivered once Microsoft is accepting mail again. We’ll post another update as Microsoft’s status changes.

  3. Monitoring

    Microsoft continues to work on restoring its services. We are monitoring delivery attempts there. Emails in “Delivery Delayed” status will continue to be retried.

  4. Monitoring

    We’re continuing to monitor delivery to Microsoft-hosted inboxes as they work to resolve the incident. Emails in a “Delivery Delayed” status will continue to be retried and delivered once Microsoft resolves the incident.

  5. Monitoring

    Microsoft 365 is currently experiencing an incident: https://status.cloud.microsoft/, which is degrading its ability to accept email. While this is not a Resend incident, it is possible to see an elevated amount of “Delivery Delay” events if Microsoft is unable to accept the email. With our Delivery Delayed events, we will retry delivery. Once Microsoft resolves its incident, sending to these addresses will return to normal.
