Winmail.dat attachments

As of recently, Microsoft attachments are coming in as winmail.dat files when I go through the email icon to get to my mailboxes. (Using gmail, the attachments come through fine.) From what I understand, this was intentional with the last ios upgrade. Wonder if there is a chance of "fixing" this? It is inconvenient to have to go to multiple places to check different types of email accounts. It was great being able to do everything I needed through the one mail icon.
