I haven't been able to find one... If you create the collection with the powershell cmdlet, you can use a combination of New-CMSchedule and NewCMUserCollection or New-CMDeviceCollection and -RefreshType -RefreshSchedule.
Here was something I wrote to randomize the refresh times when I created a large number of collections: $AddDays = Get-Random -Maximum 7 $AddHours = Get-Random -Maximum 24 $DateTime = (Get-Date).AddDays($AddDays).AddHours($AddHours) $NewColRefreshSch = New-CMSchedule -RecurInterval Days -RecurCount 7 -Start $DateTime New-CMUserCollection -Name $ColName -LimitingCollectionName "All User Groups" -RefreshType Periodic -RefreshSchedule $NewColRefreshSch Not sure if that will help or not. There isn't a -RefreshType or -RefreshSchedule switch on Set-CMUserCollection On Mon, May 20, 2013 at 2:34 PM, Todd Hemsell <[email protected]> wrote: > What powershell command updates the refresh schedule on a collection? > >
