Junk or Not
With both the older and beta versions of Outlook, the Junk filter does not seem to work well. Email from senders that I regularly check as "Not Junk," goes back into junk mail. I understand that I could add these email addresses to my contact list, but then what is the point of having a "Junk or Not" option? If the "Not Junk" option doesn't remember my choices, it's pretty much a useless feature.
