Inbox Extender has been around for some time now, adding two useful commands to your Pocket Outlook, namely Mark All as Read and Delete All, but there was one huge downside to it: Delete All would actually delete all your messages without confirmation, so a wrong tap would get you in trouble.

Safe Inbox Extender from XDA Developers fixes that: it adds the two extra commands to Pocket Outlook, but accidentally tapping on Delete All will now bring up a confirmation dialogue box warning you of your choice, where you can confirm or not the action to be taken. I personally find very useful the Mark All as Read action, where you don’t have to multiple select messages to mark them read any longer.

Download the cab, install it to your device, Soft Reset (or not, mine worked without it) and the two extended commands, Mark All as Read and Delete All will show up in the soft menu of mail within Pocket Outlook.
