A few days ago I searched for a solution to administrate contacts for several Lync 2010 users. Sorry for my english.

I found the great VBS script LyncAddContacts from Jeff on this website: expta.com. Very great tool, I appreciate Jeff’s work. But the fact of the matter that I’m familiar with Powershell, I wonder whether it is possible with Powershell and I can use my well-loved pipeline.

As the original script you have to use the DBIMPEXP utility from the Lync 2010 server to import and export contacts.

I quote the description from expta.com:

The purpose of Add-LyncContacts is to add the same contact groups and contacts to multiple users programmatically.

For example, you may want to import a contact group called “Company Contacts” that contains contacts for everyone in the company.

Here’s how it works:lync

  1. Create a template (source) user in Lync with the contact groups and contacts that you want to export.
  2. Import the powershell module Add-LyncContacts.psm1
  3. Execute the cmdlet “New-CSContactExport” to export the source user’s contacts and groups
  4. Execute the cmdlet “New-CSContactImport” to import the contact/group template to one or more users.


  • You have to run the cmdlets on the Lync server from which you will export/import the data.
  • You must be a member of the CSAdministrator security group to run this tool. This group has rights to export and import contact groups and contacts to all users.
  • You must copy the DBIMPEXP.EXE tool from the \Support folder on the Lync Server 2010 installation media to the same folder where you call the Add-LyncContacts-Modul cmdlets.
  • You must have read, write and execute rights to the folder where the Add-LyncContacts-Modul cmdlets will be called, because the script will create temporary files for editing.


  • Start Powershell with Administrator rights.
  • Import-Module Add-LyncContacts.psm1
  • Navigate to the folder where you can find the DBIMPEXP.EXE utility
  • If you use Lync Server Enterprise Edition then you have to set the required SQL server parameter

To backup all user data to a specific filename, use the following cmdlet:

New-CSContactBackup -FileName backup.xml

For the Lync Server Enterprise Edition the cmdlet will be executed like this:

New-CSContactBackup -FileName backup.xml -SQLServer sql.domain.com

where backup.xml is the backup filename and sql.domain.com is the SQL server used by the front-end pool.

Once the backup has been performed, you can begin the export/import process. First, you must export the source user’s contact groups and contacts. The following example exports this information from a user named “test” on a Lync Standard Edition server:

New-CSContactExport -SIPName test@lync.local -FileName: testExport.xml

where test@lync.local is the SIP address of the user you want to export and textExport.xml is the exported file. For a Lync Enterprise Edition server use the -SQLServer parameter.

Second, you import the contact groups and contacts to one or more user(s). The following example imports the data to a user named “test” on a Lync Standard Edition server:

New-CSContactImport -SIPName test@lync.local -FileName: testExport.xml

Lync Server Enterprise Edition:

New-CSContactImport -SIPName <a href="mailto:test@lync.local">test@lync.local</a> -FileName: testExport.xml -SQLServer:sql.lync.local

The followings two examples import the same contact groups and contacts to several SIP enabled users:

Example 1: Users from a txt file

Get-Content users.txt | New-CSContactImport -FileName contacts.xml

where the txt file looks like this:



Example 2: Get users from the ActiveDirectory

Import-Module ActiveDirectory

Get-ADUser -Filter * -Properties msRTCSIP-PrimaryUserAddress | ?{$_."msRTCSIP-PrimaryUserAddress" -ne $null} | Select-Object @{label='SIPName';Expression={$_."msRTCSIP-PrimaryUserAddress"}} | New-CSContactImport -FileName contacts.xml

where contacts.xml is the source template for the contact groups and contacts.

A nice benefit of this tool is that contacts will not get a notification that so-and-so has added them to their contact list. This is really useful in preventing unnecessary pop-ups from the Lync client.

Special thanks go to Jeff from expta.com.
