Outlook incident - emails not getting delivered
Timeline · 1 update
- resolved Jan 27, 2026, 01:00 PM UTC
We are currently aware of an upstream incident with Microsoft Outlook impacting email deliveries with several of our messaging providers over the past several days. This has been widely reported across the industry, but Microsoft has not shared any public commentary as of yet. We're looking into any ways we may be able to mitigate this until Microsoft addresses the issue. Though these issues are not causing any downtime in Stytch services, due to the popularity of Microsoft Outlook, we've created this incident for posterity for customers investigating downtime in their own systems. Customers that feel they are continuing to observe excessive deferrals and/or blocks should fill out the OLC Support request form at [https://olcsupport.office.com.](https://olcsupport.office.com/).

We are currently investigating an increase in errors in the Stytch API due to impact from an upstream provider outage..
- monitoring Nov 18, 2025, 12:01 PM UTC
Services are recovering in the upstream provider, Cloudflare. Customers may continue to observe higher-than-normal error rates if they utilized Cloudflare in the meantime..
- resolved Nov 18, 2025, 12:10 PM UTC
During [Cloudflare's 2025-11-18 incident](https://blog.cloudflare.com/18-november-2025-outage/), Stytch's services continued to operate as normal. However Stytch customers that use Cloudflare in their own infrastructure may have seen their requests to Stytch, either client or server side requests, fail to make it to the Stytch API, thus causing their auth flows to fail. Though the Cloudflare incident did not cause any downtime in Stytch services, due to the popularity of Cloudflare, we've created this incident for posterity for customers investigating downtime in their own systems..

**Issue** All SAML SSO Logins failed in the Stytch Platform. **Timeline** October 20th, 2025 16:30 - 18:01 UTC **Cause** A widespread outage in AWS created a knock-on effect that uncovered a latent certificate management issue within the Stytch SSO service. Other Stytch services, like the core Authentication API, responded appropriately in the face of downtime and continued to operate as expected. The result was that all SAML SSO login attempts during this incident returned an invalid certificate error and prevented users from logging in. **Remediation** Stytch updated the SSO service to handle certificate management so that it aligns with our other services that did not error. This reconfiguration will prevent this error from recurring in the event of AWS failure again in the future..
