Bulk move AD users to another OU

Hello,

I am trying the below script to read AD users in the TEST.CSV file and move them to OU=TEST,DC=mydomain,DC=com.

Import-module activedirectory
# Specify target OU.
$TargetOU = "OU=TEST,DC=mydomain,DC=com"

# Read user sAMAccountNames from csv file (field labeled "Name").
Import-Csv -Path c:\test\PS\AD\moveusers\test.csv | ForEach-Object {
    # Retrieve DN of User.
    $UserDN = (Get-ADUser -Identity $_.Name).distinguishedName

    # Move user to target OU.
    Move-ADObject -Identity $UserDN -TargetPath $TargetOU
}




TEST.CSV

distinguishedName
CN=Carl Rivet,OU=Users,OU=YUL,OU=_CANADA,DC=mydomain,DC=com
CN=BA Sales,OU=Users,OU=IAD5,OU=IAD_,OU=_US,DC=mydomain,DC=com
CN=Vida Poon,OU=Users,OU=IT,OU=CORP_,OU=_US,DC=mydomain,DC=com
CN=HYSynergy,OU=Service Accounts,OU=IT,OU=CORP_,OU=_US,DC=mydomain,DC=com


After the script is run, only the last user in the TEST.CSV file is moved (HYSYNERGY).  Other users shows error like this:
