Exchange 2007 SP2: HasActiveSyncDevicePartnership Always Returns True

Question

I am currently work with a customer in an Exchange Server 2007 SP2 environment. A Powershell script that is used for gathering mobile device information begins with at the mailbox level and filters with
HasActiveSyncDevicePartnership equal to true, as in -
Get-casmailbox -Filter {HasActivesyncDevicePartnership -eq $true }
We have discovered that it appears as though this flag is set to true for every mailbox account, despite the fact that only a few mailboxes have actual EAS partnerships with devices.
My understanding was that this flag should only ever return true if there is an actual ActiveSync partnership. Is there something I am missing here? Can the flag be true even if there is no (or has never been) a partnership?

Hi,
Yes, the value of the " HasActiveSyncDevicePartnership " will be set to true if there is an actual ActiveSync partnership. Also you can use the following command to
check the detail sync information such as device name,  last sync time:
Get-ActivesyncDeviceStatistics -Mailbox [email protected]
If no statistics information returns, The most probable cause 
should be that someone set the HasActiveSyncDevicePartnership to true for all mailbox users accidently. Please run the following command to change them back:
get-casmailbox |set-casmailbox -HasActivesyncDevicePartnership $false
Then set the
HasActiveSyncDevicePartnership to true for the users who have an actual ActiveSync partnership:
Set-casmailbox –identity
[email protected] -HasActivesyncDevicePartnership $true
