Getting an overview of all ActiveSync devices in the Exchange-organization

In Exchange 2007, we can get use the Get-ActiveSyncDeviceStatistics to retrieve statistics for a specific ActiveSync-device. We must supply either a device identity or a mailbox name. In Exchange 2010, the same cmdlet exists, but we also got a new useful cmdlet; Get-ActiveSyncDevice. This cmdlet lists all devices in the organization that have active Microsoft Exchange ActiveSync partnerships.

To provide a way to list all ActiveSync devices in the Exchange organization that works against both Exchange 2007 and Exchange 2010, I`ve created a script named Get-ActiveSyncDeviceInfo.ps1. The script outputs each device as an object, making it easy to work with the results. You might i.e. export all devices to a CSV-file by piping the results to Export-Csv.

You might also create graphs based on the results, like I demonstrated in a previous blog-post.

I`m aware that the script could be more effective, using Get-CASMailbox and a server-side filter to sort out only mailboxes that got the property HasActiveSyncDevicePartnership set to “true”. However, I`ve experienced that this property isn`t reliable. Several mailboxes that does have the HasActiveSyncDevicePartnership set to true doesn`t have an ActiveSync devices associated. You might want to use this approach anyway in larger organizations, although I chose to skip it and rather loop through all mailboxes.

    • Try this: .\Get-ActiveSyncDeviceInfo.ps1 | Export-Csv -Path $home\Documents\ActiveSync-devices.csv -NoTypeInformation

  2. It seems that MS devices and Android devices are not consistent in how they report anything. I can report I-phone and non-iphon but not really anything more. Have you found a way to pull what the device actually is?

  3. When running this script against mailboxes in 2007 from Exchange 2010 Powershell it is generating a ton of “version” errors.

    The Get-ActiveSyncDeviceStatistics command that you are trying to run, which is version 14, requires that the target mailbox account is on a Mailbox server that is the same version. The command wasn’t able to process your request because the target mailbox account is on a Mailbox server with version 8. Please use this version (Version: 8) of the Get-ActiveSyncDeviceStatistics command.

  5. The select-object statement gives me the error “the writeobject and writeerror methods cannot be called after the pipeline has been closed. Please contact Microsoft Support Services.” What’s up with that?
