I went from Office 2011 for Mac to Office 365 for Mac last week, and I'm really beginning to regret my decision simply because I cannot customize the ribbon in Outlook. There are no "display next message" or "display previous message" shortcuts when reading an email message. I have to click on the "x" to close my current message and then double click on the next message I want to read. With the large amount of email I have to read each day, this was a simple shortcut I used to quickly navigate through my messages. Now there is too much clicking involved. Please add this option soon.
