Project Planning & Scheduling Software -- Project KickStart
KickStart integrates with Outlook -- sort of. KS projects become Outlook task categories, and KS tasks become Outlook tasks. There's no synchronization -- KS is always the source of truth and it overwrites the Outlook categories. Without Outlook that tasks must be treated as "read only" or moved out of the KS categories.
I'm going to experiment with this a bit. I'll preface each KS project with the prefix ks_ so I know not to touch those tasks in Outlook. They will also display on my Palm (unfortunately, due to PalmOne's failures, Palm synchronization is not what it used to be ...).
