Feature overview

We're updating dynamic distribution groups (DDGs) in Exchange Online to make group membership available sooner after creation or a filter change. For DDGs with 5,000 members or fewer, membership is now populated as part of the creation or modification operation — no more waiting up to 2 hours.

Expected release date

May CY2026
