Email app with view 'All' emails feature that include sub folders?
I am new to IOS/Iphone and have installed MS Outlook for my work Exchange account. With that being said, I have alot of sub folders and would like to view as default ALL incoming emails including sub folders as the main view, that way, I don't need to literally go into the sub folders to view new emails.
I don't see that as an option in Outlook or maybe I'm mistaken.
Is there any other email app that may have this feature?
