Several other email apps have the ability to delete a message from the notification screen without having to go into the app. I know you can archive but having a delete function (or a choice of which function you want) would be awesome.

Autodownload emails rather than wait until they are opened to fetch the content from the servers.

Ability to set Group emails by sender and follow all the emails with that person.

Have the ability to have emails sent from alias account.

I need to empty my super crowded junk folder from my pc because from the phone I can only do it one message at a time and it takes forever. Please the empty folder option. (+better filters for junk would be nice too)

The embedded images in an email (NOT ATTACHED TO THE EMAIL, BUT IN THE BODY OF THE TEXT) are unable to be saved to my phone's gallery.

So it's easy to know which email address the message was sent to even before opening it.

I set up a signature on my desktop and I need this to also be synced as an option on the mobile app. It should not be necessary to recreate the signature.

Dangerous spams use a false but trusted looking address as name. The real address that actually shows its a spam is hidden behind a useless coloured circle in outlook.
