Exchange: Dynamic distribution groups now populate membership faster on creation and modification

Microsoft 365 roadmap entry

Summary

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.
