Reply To: Trapping Excel error messages in Powershell Scheduled scripts

OK, part of the confusion is that you’re looking at an error that has been wrapped in at least one extra layer of exception (MethodInvocationException, which is a PowerShell thing.) You can get at the original error like this; see if it gives you better information:

try
{
    $objExcel = New-Object -ComObject "Excel.Application" 
    $objExcel.Visible = $False
    $objExcel.DisplayAlerts = $False
    $UserWorkBook = $objExcel.Workbooks.Open($strInputFile)
}
catch
{
    $exception = $_.Exception

    while ($null -ne $exception.InnerException)
    {
        $exception = $exception.InnerException
    }

    # Display the properties of the original exception
    $exception | Format-List * -Force
}
