Deleted Items in a Shared Mailbox

I was wondering if anyone had used a flow or something else to move them from the users' deleted items to the shared mailbox deleted items. 

For testing I logged in to the shared mailbox using Outlook on the web and deleted a item. It went to the shared deleted items - which is what I wanted. 

So the problem seems to only be with the Outlook desktop client so the registry change should work. In this case items are almost never deleted from someone's phone so that shouldn't be an issue.

It is unfortunate this couldn't be done with a PowerShell command like the Sent Items can. It took about 1 minute to get all the sent items to go to the shared mailbox sent items folder but it will take several hours to get the deleted ones correct.

Thanks
