Service Disruption on Email Delivery

Update timeline

1. investigating Nov 12, 2026, 06:30 PM UTC

   On November 12, 2026, at 10:30 AM PT, the Engineering Team became aware of an issue with email delivery to some recipients, affecting customers in all Okta Preview and Production cells. We have identified the issue as a disruption at a third-party email provider, which is actively working on a fix. During this time, emails sent from Okta to affected recipients may be delayed or may not be delivered. Users waiting on verification codes may experience delays of several minutes. If available, please opt for backup verification methods such as authenticator apps. Our team is monitoring the provider’s progress. We will provide another update within the next 30 minutes, or sooner if additional information becomes available. Affected cells: okta-emea.com:1, okta.com:1, okta.com:2, okta.com:3, okta.com:4, okta.com:6, okta.com:7, oktapreview.com:1, oktapreview.com:2, okta.com:8, okta.com:9, okta.com:11, okta.com:12, oktapreview.com:3, okta.com:14, okta.com:16, okta.com:17, okta.com:18, okta.com:19, okta.com:20, okta.com:22, okta.com:23

2. identified Nov 12, 2026, 10:03 PM UTC

   The third-party email provider continues its recovery efforts, returning affected infrastructure to service and evaluating additional steps to accelerate the recovery process. Emails sent from Okta to affected recipients may still be delayed or not delivered. If available, please continue to opt for backup verification methods. Our team continues to monitor the provider’s progress. We will provide another update in 60 minutes, or sooner if additional information becomes available.

3. identified Nov 12, 2026, 11:07 PM UTC

   The third-party email provider is continuing to work on restoring service. Their actions so far have not yet provided the expected relief, and they are pursuing additional recovery approaches. Emails sent from Okta to affected recipients may still be delayed or may not be delivered. There is currently no estimated time for full recovery. If available, please continue to opt for backup verification methods. Our team continues to monitor the provider’s progress closely. We will provide another update in 60 minutes, or sooner if additional information becomes available.

4. monitoring Nov 13, 2026, 01:13 AM UTC

   The third-party provider reported that some of the underlying systems brought back online are becoming unresponsive again as traffic returns, so full restoration is taking longer than anticipated. Their engineering teams are analyzing diagnostic data to isolate the trigger and are testing traffic-limiting measures to restore service in stages. As a result, messages sent to affected addresses may still be delayed or fail to be delivered. There is no estimate for full restoration yet; where possible, please rely on backup verification methods. We are actively monitoring recovery and will provide another update in 120 minutes, or sooner if new information becomes available.

5. monitoring Nov 13, 2026, 02:13 AM UTC

   The third-party email provider observes improvement with remediation applied and will continue to restore services gradually. During this time, messages sent to affected addresses may still be delayed or fail to be delivered. There is no estimate for full restoration yet; where possible, please rely on backup verification methods. We are actively monitoring recovery and will provide another update in 120 minutes, or sooner if new information becomes available.

6. monitoring Nov 13, 2026, 04:57 AM UTC

   Some users may continue to experience intermittent email delivery issues due to an ongoing incident with a third-party provider. The provider has applied several traffic management updates that have improved stability in certain regions, though service levels are not yet consistently restored across the board. They are currently assessing next steps for full recovery. If available, please continue to opt for backup verification methods. We will share another update as soon as more information becomes available. Thank you for your patience.

7. monitoring Nov 13, 2026, 04:55 PM UTC

   The third-party provider reports that they are addressing the final residual impact and monitoring service health to confirm stability. Additionally, the provider has stated they have found no evidence of malicious activity related to this incident. During this recovery phase, emails sent from Okta to affected addresses may still be delayed, with delivery gradually returning to normal. Please continue using backup verification methods where possible. We are closely tracking the vendor’s progress and Okta delivery metrics, and will post another update when we have more details to share.

8. monitoring Nov 13, 2026, 06:55 PM UTC

   Our third-party provider has reported that they have addressed the underlying root cause and are seeing broad recovery and stability across their core network. They are currently rolling out gradual restorations to remaining customers and regions. Because they are validating stability at each stage to ensure security, recovery is taking slightly longer than anticipated. Depending on your workflow, you may still experience delays in email delivery or issues accessing mailboxes via Outlook on the web, desktop, or mobile. If available, please continue to opt for backup verification methods. We are closely monitoring our provider’s progress and will provide another update as soon as further information becomes available or services are fully restored.

9. monitoring Nov 13, 2026, 08:27 PM UTC

   The third-party provider reports that its infrastructure is stabilizing. The provider is now working through a backlog of queued messages and balancing traffic across its systems. While sign-in and access to its services may improve first, message delivery will take longer to catch up. Email sent from Okta to affected addresses may therefore still arrive late, and messages that were held up may be delivered once the backlog clears. The provider has not yet shared a time for full recovery. Until delivery returns to normal, please continue using backup verification methods where possible. We are closely following the provider's progress and Okta's delivery and will post another update when we learn more.

10. monitoring Nov 13, 2026, 10:22 PM UTC

    The third-party provider reports that recovery has remained steady across the affected environments. Because of the severity of this disruption, the provider plans to keep a close watch for an extended period to confirm nothing further is needed. The provider is also tracking the backlog of email built up during the disruption and will not consider the issue closed until every message has been processed. Some email sent from Okta to affected addresses may therefore still arrive late. Backup verification methods remain available. We are watching the provider’s progress and Okta delivery, and will post another update when we learn more.

11. resolved Nov 14, 2026, 04:09 PM UTC

    The third-party vendor has completed its work on the underlying issue and reports that the disruption affecting email delivery has been fully resolved. Additional root cause information will be forthcoming.
