"body": "# Summary\n\nOn March 18, 2026, a small subset of CodeTwo customers experienced temporary issues with email delivery. The incident was caused by a Microsoft networking and DNS\u2011related issue within Microsoft 365 infrastructure and was not the result of a failure in the CodeTwo service.\n\n# Impact\n\n* Only a\u00a0limited number of customers\u00a0were affected.\n\n* The issue occurred intermittently.\n* The impact was limited to customers whose mail flow depended on Microsoft 365 services affected by the incident.\n\n# Root cause\n\nMicrosoft confirmed that the incident \\(ID\u00a0MO1255228\\) was caused by a temporary issue with their networking infrastructure, where part of the infrastructure intended to handle production traffic was only partially reinstated. This led to DNS and load\u2011balancing issues, affecting services such as Exchange Online.\n\nThe incident originated entirely within\u00a0Microsoft\u2019s infrastructure\u00a0and was outside of CodeTwo\u2019s control.\n\n# Resolution\n\nMicrosoft manually reinstated the full networking infrastructure and confirmed service health recovery. Following this action, telemetry indicated stable and healthy service operation.\n\n# Why CodeTwo was affected\n\nCodeTwo services integrate directly with Microsoft 365 and Azure and rely on Microsoft\u2011managed DNS and networking components.  DNS failures at the Microsoft platform level affect all services integrated with Microsoft 365, including third\u2011party solutions.\n\nThere is no technically viable way for any Microsoft 365-integrated service to be fully immune to platform\u2011level DNS or networking failures on Microsoft\u2019s side.\n\n# Preventive measures\n\n* CodeTwo services are\u00a0monitored 24/7/365.\n\n* We operate\u00a0redundant and failover\u2011capable infrastructure.\n* In case of Microsoft\u2011side incidents, we take all actions\u00a0within our control\u00a0to minimize customer impact, including traffic rerouting where technically possible.\n\nMicrosoft stated that this type of incident has been\u00a0extremely rare\u00a0and committed to improving safeguards to prevent similar events in the future.\n\n# Current status\n\nMicrosoft has confirmed that the affected services were fully restored and operating normally. No further issues related to this incident have been observed.",
