For auto-sorting mail I use Sieve. It seems to be available for Outlook. It's a protocol for a mail client to talk to a server, along with a language for making processing scripts, which is a bit awkward if you don't care for code. But there are nice front-ends that can magic the code away. I realise that wasn't exactly what OP was asking, but one way of handling mail you don't have time to read is to file it, and Sieve is an auto-filer. I once had a colleague with a stack of 3 inboxes on his desk, labelled "Too Boring", "Too Difficult" and "Too Late". You could try something like that :-)
