Everyone, I've been made aware that Workfront intents to stop support and development on non-Outlook365 platforms, to include 2010 and 2013. If you're like me, and work for a company with "sensitive" information that will preclude the use of a web based platform, and will never migrate to Outlook365, you'll lose support for the Outlook plug-in functionality. That said, WF has said that if there is enough support to keep the plug-in, they would consider and potentially support the app in perpetuity. Please chime in here if you need the continued support for the plug-in.
ViaSat will continue to need the plug-in and it's support in perpetuity!!!
-Edit-
I'm bumping this as WF is again scheduling the removal of support for the desktop app in leu of Outlook 365, which is the web based platform, only... If you want/need this service, please comment here and vote to keep this feature supported in the platform!!!
