I want to use an error to modify a file.

# Import new users
$ADUserfiles = Get-ChildItem $userfolderpath\*.csv
foreach ($Ufile in $ADUserfiles)
{
  # Import new users
.\tabcmd createusers $Ufile $TabParam
}

The snippet of code above uses a command line tool to add users to to my application.   I have run into a problem.
When the script gets to a particular user(s) it will fail and it skips that entire file instead of just skipping that one ID.   This occurs in 2 of my files so far while testing.  I can't modify tabcmd, it's part of an application.

What I would like to do is capture this error and use it to delete the row containing that ID then have the script rerun the file.

===== Error importing processing users CSV file (file reference: 5)
No Active Directory account named <i>usera usera</i>.

I thought about using Try/Catch but I don't know how to capture the error and pass just the id contained in the error to a variable that I can then use to delete the row from the file.   There could be many different problem id's contained in 1 or many different files.  If it has to loop through a file once or many times that is ok with me.  

Any help is appreciated.
