This was very useful thank you.

I am currently restoring ~150,000 items. I've used Co-Pilot to add a counter to the my script. You may find it useful

# Get the total number of rows in the CSV file
$TotalRows = (Import-Csv -Path:"$Path").Count

# Initialize a counter for the current row
$CSVRow = 0

# Loop through each row in the CSV file
@($(Import-Csv -Path:"$Path")).ForEach({
    $csv = $PSItem

    # Increment the counter by one
    $CSVRow++

    # Write the information message with the desired format
    Write-Information -MessageData:"Restoring item $CSVRow of $TotalRows. Item $($csv.Title)"

    # Restore the recycle bin item with the given ID
    Restore-RecycleBinItem -Id $($csv.ID)
})

Hi @SharkEyes93 thank you for your suggestion.

There is a newer better version of this script which can be found at PNP Script Samples. It batches and runs a bit quicker.

Feel free to Co-pilot the script and improve on it, I think you will get a PNP PowerShell script badge if you make any updates that get accepted into the Pull Request.
