More Multi-valued Parameters in PowerShell (SourceTransportServers in Set-SendConnector)
In my first article on Multi-valued Parameters in PowerShell, I discussed a certain class of array parameters that Exchange 2007 uses many times - the [System.Object] (i.e., array of arbitrary elements) class for RemoteIpRanges.
Unfortunately, that isn't the only multi-valued type used by PowerShell for Exchange Server 2007. There are actually quite a few of them.
Another type that comes up fairly often is SourceTransportServers. This is used by the Set-SendConnector cmdlet among others. It is a collection of a specific type of objects that Exchange 2007 refers to as ADobjectIDs.
An ADobjectID is actually quite similar to a System.DirectoryServices.DirectoryEntry - however, in comparison, this type has very few populated properties. The fact that the property list for ADobjectID is quite small indicates the reason why Exchange uses this type instead of System.DirectoryServices.DirectoryEntry - the population of a few types is much more efficient than the population of all the types present for a DirectoryEntry.
Populating and updating SourceTransportServers is a common idea, especially when you are using provisioning scripts to completely deploy new servers. Here is an example of PowerShell code that you can use to do this:
$newhub = Get-ExchangeServer "newhubserver"
$adobject = New-Object Microsoft.Exchange.Data.Directory.ADobjectID $newhub.distinguishedName
$a = Get-SendConnector "Internet Email"
$a | Set-SendConnector
Until next time...
