How can I delete more than 100 quarantined emails at a time using PowerShell?

Hi All,

I currently run a PowerShell script to delete quarantined emails (when my total exceeds 100 emails). Happy to do this, but it seems I can only bulk delete 100 emails at a time. 

Anyone find a work around for this? Will Microsoft come up with a new parameter or option to bulk delete more than 100 at a time.

Reason I ask is because I have had days where a users credentials are compromised, causing the quarantine log to explode (800 - 1800 quarantined emails). Running the script is better than clicking 100 emails at a time, but it would be nice to have the option to delete 'All'.

Thanks

Che
