Microsoft Launches Public Preview of Exchange Online Admin API

Microsoft has announced the public preview of the Exchange Online Admin API, a modern REST API that gives IT teams scalable, service-account–friendly control over mailbox and recipient management. The Admin API is designed to assist users who rely on EWS (scheduled for deprecation in October 2026) for a subset of Exchange administrative tasks. Microsoft's new Admin API supports these functionalities: OrganizationConfig, AcceptedDomain, Mailbox, MailboxFolderPermission, DistributionGroupMember and DynamicDistributionGroupMember.

The shift comes as enterprises increasingly automate identity and messaging operations across hybrid and multi-geo environments. Microsoft’s update is a strategic modernization for enterprise IT teams preparing for long-term automation and zero-trust governance. General availability for the Admin API is yet to be announced.
