Lync PowerShell Script to Mass Enable Users

* Updated 1/22/15 - I added the option to add dial plan and voice policy as well to the script
* Updated 6/20/13 - I forgot to add the dash in set-csuser on the bottom script so the enable-csuser cmdlet would fail.

Of course there is always a need to mass enable users for Lync once you have Lync deployed in your environment. The easiest way to mass enable users for Lync is via a PowerShell script and a CSV file with the user information. 

To enable PC-to-PC users only
Here is a script I created to mass enable users:

if ($args[0] -eq $null)
    {
    $userNameFile = read-host "Enter the full path of the .csv file with the user information."
    $userNameFile  = $usernamefile -replace '"',""} 
else 
    {$usernamefile = $args[0]}
if ($userNameFile -ne "") 
    {$csv=import-csv $userNameFile} 
else 
    {"Could not find a valid .csv with the user information."
    exit}
foreach($c in $csv)
# enable for lync
{
"Enabling " + $c.Identity + " for Lync 2010"
Enable-csuser -identity $c.Identity -registrarpool $c.RegistrarPool –sipaddresstype $c.SipAddressType -sipdomain $c.SipDomain
}

This script will enable the users with basic PC-to-PC configuration. This script allows for organizations with multiple SIP domains and multiple pools with the columns in the .csv file for RegistrarPool and SipDomain. The .csv file will look like this:

Identity	RegistrarPool	SipAddressType	SipDomain
John Doe	PoolFQDN.Domain.com	EmailAddress	SIPDomain.com

To enable Enterprise Voice users
To enable the users for Enterprise Voice, we will make the following addition (highlighted in yellow and green) to the above script. The green highlighted section is optional if you have extensions set up in your LineURI’s like tel+12815551234;ext=1234. You can omit this section and remove the Extensions column from the .csv file if you are not using extensions in your LineURI’s:

if ($args[0] -eq $null)
    {
    $userNameFile = read-host "Enter the full path of the .csv file with the user information."
    $userNameFile  = $usernamefile -replace '"',""} 
else 
    {$usernamefile = $args[0]}
if ($userNameFile -ne "") 
    {$csv=import-csv $userNameFile} 
else 
    {"Could not find a valid .csv with the user information."
    exit}
foreach($c in $csv)
# enable for lync
{
"Enabling " + $c.Identity + " for Lync"
$lineuri = "tel:+1" + $c.PhoneNumber + ";ext=" + $c.Extension
Enable-csuser -identity $c.Identity -registrarpool $c.RegistrarPool -sipaddresstype $c.SipAddressType -sipdomain $c.SipDomain 

# Pause for 30 seconds for AD Replication
write-host -foregroundcolor Green "Pausing for 30 seconds for AD Replication"

Start-Sleep -s 30

Set-CsUser -Identity $c.Identity -enterprisevoiceenabled $True -lineuri $lineuri
Grant-CsDialPlan -Identity $c.Identity -PolicyName $c.DialPlan
Grant-CsVoicePolicy -Identity $c.Identity -PolicyName $c.VoicePolicy
}

As you can see, the script turns the 10 digit phone number into E.164 format and adds the extension (if needed) and then sets it as the LineURI for the user. The .csv file will have the following columns added for this script:

PhoneNumber	Extension	DialPlan	VoicePolicy
2815551234	1234	HoustonDialPlan	HoustonVoicePolicy
