If you are looking for an easy way to get ActiveSync statistics for users who have successfully sync their devices since a particular date, you can use the following cmdlet:
(Get-CASMailbox -ResultSize Unlimited -Filter {HasActivesyncDevicePartnership -eq $True}) | ForEach {Get-ActiveSyncDeviceStatistics -Mailbox $_.Identity | Where {$_.LastSuccessSync -ge (Get-Date “01/01/2012”)}} | Export-Csv E:\Reports\”ActiveSyncStats_$(Get-Date -f ‘yyyyMMdd’).csv” -NoTypeInformation
In this case, we are exporting statistics for all the devices that successfully synced with Exchange since the 1st of January 2012 to a CSV file.
