Need help with Get-Contact powershell command

Posted on 2010-08-19
Last Modified: 2012-05-10
We have about 1200 Contact objects in our AD. I need an Exchange Powershell command (Probably the Get-Contact) to search through all these Contacts and find out which ones are members of a particular Distribution List. I am sure it's something like Get-Contact | where-object...etc.etc. Does anyone have this command available. Like if I want to find out all Contacts that are members of the Distribution Group "All Employees". What would the command be.
Of course, if I have to approach it the other way, like search all DL's where membership contains a certain Contact or group of Contacts, that would work also but it would be more cumbersome because I would have to pass it a list of Contacts. LIke search all DL's and return a list that has any of these Contacts. Easy one for a powershell Guru. We are running Exchange 2007 SP1.

the following can be saved as Get-ContactMemberOf.ps1 then run

function Get-GroupMembership($email)
{	# Verify arguments
	{	Write-Host "You must specify the email address of the user." -ForegroundColor Yellow

	# Set the LDAP URL to the container DN specified on the command line
	$LdapURL = "LDAP://dc=contoso,dc=com"

	# Initialize a DirectorySearcher object
	$searcher = New-Object System.DirectoryServices.DirectorySearcher([ADSI]$LdapURL)

	# Set the attributes that you want to be returned from AD
	$searcher.SearchScope = "Subtree"

	$filter = "(mail=" + $email + ")"
	$searcher.Filter = $filter

	# Run the LDAP Search request against AD
	$contacts = $searcher.FindAll()

	foreach ($contact in $contacts)
	{	[string]$name = $contact.Properties.displayname
		$objContact = $contact.GetDirectoryEntry()
		if($objContact.memberof.count -ne 0)
		{	foreach($m in $objContact.memberof)
			{	$m

Get-GroupMembership $args[0]

Got this error: Also, is it possible to pass a list of addresses instead of one at a time.

Closest I can guess...I don't have EMS available right now...
get-recipientt | where{$_.addresslistmembership -like "blah*"}

make sure your LdapUrl is correct

you could take run
"contact1","contact2" | get-contactmemberof.ps1 $_

sorry it would be
"contact1","contact2" | ForEach-Object { $_; .\memberof.ps1 $_ }

of course you could use a text file or csv

Thanks. The LDAP was incorrect. The command works well but I had problems with the input. When I specify just one Contact like "Contact1" | get-contactmembershipof.ps1, it just comes back and tells me to specify an email address. I included the $_ but no difference. I am a noob at scripting hence the questions. Also, is there any way to specific an input file like a list of Contact names in notepad or Excel?

Sorry but I don't understand your last post. What are you saying?

you need to update the following line
$filter = "(mail=" + $email + ")"

if you are using lastname for your contact it would be:
$filter = "(sn=" + $email + ")"

if you are using displayName it would be:
$filter = "(displayName=" + $email + ")"

Thanks for all your help on this.
This is what I am typing:
"Mickey Mouse" | ForEach-Object { $_; .\getmembershipof.ps1 $_ }

This is the error it returns. ( I played with the name of the script but verified it is correct)

The term '.\getmembershipof.ps1' is not recognized as the name of a cmdlet, function, script file,
or operable program. Check the spelling of the name, or if a path was included, verify that the pat
h is correct and try again.
At line:1 char:60
+ "Mickey Mouse" | ForEach-Object { $_; .\getmembershipof.ps1 <<<<  $_ }
    + CategoryInfo          : ObjectNotFound: (.\getmembershipof.ps1:String) [], CommandNotFoundEx
    + FullyQualifiedErrorId : CommandNotFoundException

Is my syntax correct? As I mentioned, I am at noob at this. Also, you did say you can use an input file. What is the command for that?

make sure your shell is in the directory where the ps1 file resides
you can always change it to
"Mickey Mouse" | ForEach-Object { $_; c:\scripts\getmembershipof.ps1 $_ }

like the disney ref

Perfect!! That worked. Just one last question. You mentioned you can use an input file. I have both Excel and Notepad versions of a list of users. Without typing all the names in, how would I use the file as an input to this command?

yes, with the following

get-content c:\contact.txt | ForEach-Object { $_; c:\scripts\getmembershipof.ps1 $_ }
