Service Alert: Microsoft Email Delivery Delays — November 12-13, 2026

Microsoft is currently experiencing a widespread outage affecting Outlook, Exchange Online, and other Microsoft 365 services. As a result, emails sent to recipients using these services may be delayed until Microsoft resolves the issue.

If your mailing list includes a significant number of Microsoft email users, you may notice temporarily lower open and click rates while deliveries are delayed.

There is no need to resend your campaign. Direct Mail will automatically retry temporarily delayed deliveries until Microsoft's servers are accepting mail again. No action is required on your part.

For updates, visit Microsoft's Service Status page or Microsoft 365 Status on X. We'll also update this notice as more information becomes available.
