Add the ability to integrate the Project Task with my Outlook Tasks without a 3rd party app, add in or a copy/paste...
Ben Howard commented
Microsoft have tried this in the paste, there was an Outlook add-in back in Project 2007, and then 2010 had Exchange Sync. Ultimately these haven't been a success, but there is a still a requirement out there, and some 3rd party apps do exist, such as www.applepark.co.uk/p2o. Disclaimer, this is my software.
Please, this is an important aspect of our ability to collaborate with everyone who are assigned tasks. Having task show up in their Outlook application helps with them being more visible and thus acted upon in a timely manner.
