Windows Mobile Devices Gathering error "The Windows PowerShell snap-in 'Microsoft.Exchange.Management.PowerShell.Admin' is not installed on this machine" when gathering against Exchange 2007 servers.
Exchange 2007 Management Tools Service Pack 1 or later is not installed on the Task Execution (MessageStats) server that the Device gathering is running from. The Exchange 2007 Management Tools SP1 or later might also appear to be installed but could be missing some components or are corrupted.
Install Exchange 2007 Management Tools Service Pack 1 or later on the Task Execution (MessageStats) server that the Device gathering is running from. If they already appear to be installed reinstall them or install a higher version (e.g. Excchange 2007 Management Tools SP2)
