How to sync outlook tasks and todoist
Unfortunately, it's not possible right now. There is no interaction between Outlook Tasks and Todoist as our plugin can only be used as an alternative to Outlook's Tasks feature.
We may consider adding such option in the future, though, and you're welcome to vote for this request in our Votebox: http://todoist.com/Vote/showProposal/194/
This would be a very useful feature, given that outlook also synchronizes with e-mail accounts, iphone, mobile devices etc.
It is not possible to vote anymore, so I post a comment here. :)
