Using the outlook purge feature

So I literally just noticed the delete function on outlook only marks items for deletion and doesn't actually delete them.

wtf, why wouldn't a delete function actually delete items and HOW do I purge all items from the delete queue without creating a script myself you lazy %&#!'s, because as a dev I'm 100% sure omitting the check all button was intentional so now I have to click purge one by one?!?!!?!

my process:

Delete from inbox

Delete from trash

Now I have to purge every individual email manually, wtf? I'm totally changing email clients if their isn't an easy way to delete all. Also shift select functionality doesn't work on that section of the online email client, I wonder why (sarcasm).
