Looking for a script to retrieve all mail contacts and its mail group memberships RRS feed

  • Question

  • Need to inventory all contacts (external recipients) and find out if each is in any of DLs.  I can get a list of mail contacts (Get-MailContact).  But Exchange 2016 mail contact object has no attribute for group memberships.  Looks like I have to query AD for object type of Contact.  Is that correct?  The query has to be based on display name since mail contact has no AD account (SAM ID).  Can anyone recommend a script?

  • 1) how to export display name, email address along with memberof?  

    2) the output of memberof is listed as LDAP format, such as CN=xx, OU=xxx, DC=xxxx. How can I make it just list the group name?

    3) I found some contacts are in more than one groups.  From the output of memberof I think it only showed the primary group.

  • Hi,

    Thanks for your question.

     Please refer the script below:

    $contacts=Get-ADObject -Filter "objectclass -eq 'contact'" -Properties *
    $ADgroups=$contacts | select -ExpandProperty memberof | Get-ADGroup | select -ExpandProperty name
    $contacts | select -Property displayname,mail,@{n="memberofgroup";e={$ADgroups}}

    Best regards,


    Just do it.

  • Hi Lee,

    I tested the commands.  Somehow, the output of "memberofgroup" showed each contact with the same groups, multiple groups.  And after the 3rd group name, the 4th one only showed partial.  Any idea how to fix it?

    Thanks for your reply.

    Sorry. I have changed my script.

    foreach($contact in $contacts)
    $ADgroups=$contact | select -ExpandProperty memberof | Get-ADGroup | select -ExpandProperty name
      $contact | ft -Property displayname,mail,@{n="memberofgroup";e={$ADgroups}} -Wrap  

    Best regards,


    Just do it.
