It was working find the first time I downloaded it. Then I turned off from Outlook. Now I cannot turn it back on.
if you're using Outlook 2010, please go to Options -> Add-ins, click on the "Go" button next to the "COM Add-ins" drop-down menu and you'll see a list of your adding with check boxes next to them. Check Todoist and it should re-activate immediately.
If you're using Outlook 2007, the "Add-ins" section will be in the Trust Center accessible through the Tools menu.
I DO SEE THE BUTTON NOW "ADD TO TODOIST." HOWEVER, I DO NOT SEE THE TASK PANEL. SO I CANNOT ADD NEW TASK OR ANY OF THAT.
