I'm guessing you're referring to the Outlook to Workfront integration...? That has not been working for me in the desktop version of Outlook, but it does work in the web version. I talked to someone else last week who was having the same issue that I'm having. I'm going to try to make time to submit a ticket today.
If it's the Outlook integration you're looking for, it seems to be working this today! I was going to grab some screenshots and submit a ticket but I got right in.
