Can I import existing Outlook Tasks into todoist?
Unfortunately, that's not possible. You can only install the Todoist plugin and add tasks from emails in Outlook or add the Todoist iCal feed (with Premium) to Outlook's Calendar, but it's not possible to import Outlook's tasks into Todoist.
That's a shame is I would love that feature and pay you guys instantly if it did it. With a few tasks it's not so bad - i have staff with over 3000 so manually moving them over would be a nightmare for them.
For me, lack of this feature is a show stopper, sorry...
