Microsoft Defender XDR

Updated October 2, 2026: We have updated the timeline. Thank you for your patience. [Introduction] We are enhancing how Microsoft Defender for Office 365 identifies and manages promotional email. Promotional messages will be tagged as “promotions” (previously “Bulk” in preview) and can be moved automatically to a new Promotions folder. The system learns from user actions, such as moving messages into or out of the Promotions folder and applies those preferences to future messages. These improvements reduce inbox clutter and help users stay focused while still receiving promotional content they want. [When this will happen] Public Preview (Limited): We will begin rolling out in mid-April 2026 and expect to complete by mid-May 2026 (previouslyend of April). To be included in the public preview program, send an email to BulkMailPreviews@microsoft.com indicating: Organization name, Tenant ID

Microsoft Viva

Updated September 30, 2026: We have updated the content timeline. Thank you for your patience. [Introduction] Viva Engage will stop sending email notifications to users who do not have a valid mailbox or routable email destination. Previously, email notifications could still be attempted for these users, resulting in repeated delivery retries, increased load on email systems, and, in some cases, delays to important business communications. This change reduces unnecessary email traffic, improves delivery efficiency, and helps ensure important communications are delivered reliably and on time. Users with supported mailbox configurations, including cloud mailboxes, on-premises mailboxes, shared mailboxes, and other routable email destinations, will continue to receive Viva Engage email notifications as expected. Notifications delivered through supported channels such as Microsoft Teams rema
