Dynamic Distribution Groups report in the new Exchange admin center in Exchange Online

The Dynamic Distribution Groups report in the new Exchange admin center provides insight into the usage of dynamic distribution groups for your organization. You can find this report at Reports > Mail Flow in the new EAC.

Note

By default, the report shows data for the last 30 days. If the report is empty, try changing the date range.

For permissions that are required to use this report, see Permissions required to view mail flow reports.

By default, the report shows data for "Used" Dynamic Distribution Groups. If the report is empty, try changing the filter to show "All" or "Unused" Dynamic Distribution Groups.

The table lists the dynamic distribution groups and the number of times it was used based on the date filter and the filter that allows you to select All, Used, or Unused. If you select All, it lists all dynamic distribution groups whether it was used or unused based on the date filter. If you select Used, it lists only the dynamic distribution groups that were used based on the date filter. If you select Unused, it lists only the dynamic distribution groups that were unused based on the date filter.
