Hi,
When I try to use the script, I get below error,
Exception calling "BypassLocks" with "2" argument(s): "Attempted to perform an unauthorized operation."
On Line:
[Microsoft.Office.RecordsManagement.RecordsRepository.Records]::bypasslocks($item, $checkout)

Even though executing the script as administrator, I have Site Collection Administrator rights on the site. I am still getting this error.
Can you help me.

Thanks a lot.. I was stuck with this for 2days and finally this code helped 👍
