I cannot believe that Outlook still has no unified Inbox. MS have done it in Office 2011 Outlook for Mac, Apple have it on iPads, iPhones, etc. so why do we poor Windows users have to suffer?
It is a real pain to still have to click on 4 inboxes to see my mails. I've tried doing this by introducing rules that move incoming mails to a new folder, but that didn't really work with IMAP accounts.
There must be a solution to this as I can't believe we've gone on so long without it.
