Microsoft Outlook for Android quietly gets a 'Delete' button in the notification area.

Microsoft has quietly added a much-requested feature to Outlook for Android which lets users quickly delete an email right in the notification area. Now, Outlook users will get the options to Archive, Delete, and reply to emails in Android's notification area without having to open the Outlook app first. Prior to this update, users could only archive and reply to messages. 

The addition of a 'Delete' button to the Outlook notification is very useful for situations where the provided preview is more than enough and you don't need to take any further action on the email. I for one surely welcome the 'Delete' button.

I'm not sure if this feature is being deployed through an update or is just a server-enabled feature. Either way, you can always download Outlook for Android in Google Play Store.
