Closed outlook add on by pressing the red x. Now the add on will not restart. Is there a manual ?
if you're using Outlook 2010, please try to go to the "Add-Ins" tab at the top and click on the "Todoist" button. If you're using Outlook 2007 or it won't work, go to the Add-Ins settings (it could be in the "Trust Center" in Outlook 2007 and in the Options in Outlook 2010), then click on "Go" at the bottom next to the "COM Add-Ins" drop-down menu and you'll see a list of your plugins with check-boxes next to each. Please check the box next to OutlookTodoist and the plugin should reappear.
The box is checked but the to list is not visible. I did restart outlook. It sems like the view of the to list is not being shown.
please try to uncheck it, confirm (to close the Options menu), then go to the options again and check it back (and confirm again).
If this won't help, go to your system's Control Panel -> Add/Remove Programs, uninstall "OutlookTodoist" and then reinstall it again.
Found the problem -I had to check ToDoList in view
