Microsoft is retiring Exchange Web Services (EWS) in Exchange Online, with a phased shutdown beginning October 1, 2026, and complete retirement by April 1, 2027. You must migrate your applications to the Microsoft Graph API before the final deadline to maintain access to Exchange Online mailboxes. This retirement only affects Exchange Online in Microsoft 365 environments and does not impact on-premises Exchange Server installations. Organizations using EWS-dependent applications face service interruptions unless they transition to supported alternatives. The nearly 20-year-old protocol no longer meets modern security, scale, and reliability requirements.

Microsoft has introduced trust-based enhancements to the Teams Admin Center (TAC), designed to simplify app security and compliance management for IT administrators. These updates, known as Trust Through Certification, enable you to quickly identify trusted applications, enforce organizational standards, and streamline governance workflows through features such as "apps to consider allowing," security compliance filters, and Microsoft-certified app collections. The enhancements build on existing foundational features while adding dedicated trust indicators that consolidate security signals in a centralized dashboard. You can now evaluate apps based on industry-standard certifications without leaving the Teams Admin Center, reducing the time spent on manual reviews and cross-checking vendor documentation.
