BlackBerry devices activity can be gathered by ActiveSync Report Pack if the BES server is using ActiveSync protocol.
There is no need to have the BB report pack installed for connection to BES 10 or 12
You can check if the BB devices are shown in the Report Packs/Exchange Active Sync/Devices/Device Inventory report.
If yes, the activity of the BB device is expected to show in Exchange ActiveSync Email Activity Report.
