Im trying to see if I can use Try Catsch to move AD accounts. Sometines you will have accounts that already exist in the destination container. I can use Try Catch and I can see the accounts that cannot be moved. However, I cant seem to collect them so that I can re-process them in a different way
$aduser | % {

try {
   move-qadobject $_.dn -newparentcontainer $ou | out-null
}
catch {
   $problemusers += $_.dn
}

$problemusers is blank


try {
   move

Hmm don't use Try / Catch, they do the wrong thing for this really. That is, they trap unhandled exceptions and aren't the best way to catch output from CmdLets throwing terminating errors.

Perhaps try:
Move-QADObject $_.DN -NewParentContainer $ou -ErrorAction SilentlyContinue | Out-Null
# Test whethe the last command succeeded with the reserved variable $?.
# Negated with !, testing for $? set to False
If (!$?) {
  $problemusers += $_.dn
}

Open in new window

You could also check for something before moving, worth noting even if it's an approach you wish to use :)
If (!(Get-QADObject $_.Name -SearchRoot $OU)) {
  Move-QADObject $_.DN -NewParentContainer $OU | Out-Null
}

Open in new window
