You are seriously over complicating things if you're just going to use a static location for your CSV file.
$csv = Import-CSV D:\lync_creation\userlog.csv
foreach($c in $csv){
"Enabling $($c.Identity) for Lync 2010"
Enable-csuser -identity $c.Identity -registrarpool pool01.west.com –sipaddresstype EmailAddress
}
write-host "Press any key to continue..."
$x = $host.UI.RawUI.ReadKey("NoEcho,IncludeKeyDown,AllowCtrlC")
The first line imports the CSV file into a variable.
The next 4 loops through all entries in that variable, write the host who it's enabling and then enables the person.
The last 2 lines give a Press any key to continue message and then waits for a key press before continuing.
