Type: Incident Jan 27, 13:00:00 GMT+0 - Resolved - 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/)
