Exchange: Dynamic distribution groups now populate membership faster on creation and modification
Dynamic distribution groups with 5,000 members or fewer now populate membership immediately upon creation or modification, eliminating the previous up-to-2-hour delay. Larger DDGs continue to populate asynchronously.

Microsoft's description
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.
