I have a folder in my Outlook in which I store certain emails. Somehow, I managed to convert this to an archive folder. The icon is a little file cabinet drawer instead of a folder. It appears normal on my Windows Outlook.com app, but on my 2 android devices (phone and tablet) the icon is the archive icon. I'm trying to convert the entire folder back to normal. I've been able to find directions on de-archiving individual messages, but nothing to do the entire folder.
