The Inactive Distribution Groups report shows you a list of all mail enabled distribution Groups which have not received any email messages over a particular time period.

This report is useful in identifying groups that are no longer used or required.
You can use the date selection tool at the top of the report to change the time period of the report.  For example, if you select 60 Days the report will update to show you mail enabled distribution groups that have not received any email messages for 60 days.
Select whether to show number of emails (items) or size in MB through the button to the top right of the screen.
Note: As we collect data every day for the previous 24 hours, data will be only available for the length of time you have been a Radar for Office 365 customer.  For example, if you started using the reporting application 30 days ago you will have access to 30 days worth of data.  This time period will increase the longer you use the product.
Also, this report can be customized, filtered, emailed and scheduled like all our other reports.
