The Mobile ActiveSyncs Per Day report shows you the number of mobile devices that synced over the previous 30 days. The chart shows a comparison between how many devices there are, and how many of them logged in per day.
Modifying the Chart
By default, this report displays the information in a line graph. You can change this to a bar graph by selecting the icon to the bottom right of the chart, and hide or show the different series items by selecting their names in the legend. You can find more information on modifying the chart at this support article.
The Data Table
The data table lists each date, the total number of devices, and the number that synced. You can add, remove or re-order these columns to display the information in a custom way.
As with all of the reports, this information can be customized, filtered and scheduled.
