List Number of Mailboxes per Exchange Server

Thursday, April 23rd, 2009

Another powershell script. This time making use of the .NET DirectorySearcher class. The title pretty much says it all – the output from the script lists each Exchange server in the organization with the number of mailboxes hosted.

function GetExchangeServers()
{
	$RootPath = "LDAP://" + $RootDseObj.configurationNamingContext;
	$RootObj = New-Object DirectoryServices.DirectoryEntry $RootPath;
	$Selector = New-Object DirectoryServices.DirectorySearcher;
	$Selector.SearchRoot = $RootObj;
	$Selector.pagesize = 1000;
	$Selector.Sort.PropertyName = "name";
	$Selector.filter = "(objectClass=msExchExchangeServer)";
	$Results = $Selector.findall();
	foreach($AdObj in $Results)
	{
		$AdObj.properties | Write-Output;
	}
}
 
function GetMailboxesOnServer($server)
{
	$RootPath = "GC://" + $RootDseObj.rootDomainNamingContext;
	$RootObj = New-Object DirectoryServices.DirectoryEntry $RootPath;
	$Selector = New-Object DirectoryServices.DirectorySearcher;
	$Selector.SearchRoot = $RootObj;
	$Selector.pagesize = 1000;
	$Selector.filter = "(msExchHomeServerName="+$server["legacyexchangedn"]+")";
	$Results = $Selector.findall();
	$server["name"][0] + ": " + $Results.Count;
}
 
cls;
$RootDseObj = New-Object DirectoryServices.DirectoryEntry "LDAP://RootDSE";
GetExchangeServers | foreach {GetMailboxesOnServer($_)};
