$upAttributeValue = “http://get-spscripts.com”

#Get site objects and connect to User Profile Manager service
$site = Get-SPSite $mySiteUrl
$context = Get-SPServiceContext $site
$profileManager = New-Object Microsoft.Office.Server.UserProfiles.UserProfileManager($context)

#Check to see if user profile exists
if ($profileManager.UserExists($adAccount))
{
    #Get user profile and change the value
    $up = $profileManager.GetUserProfile($adAccount)
    $up[$upAttribute].Value = $upAttributeValue
    $up.Commit()
