I down the outlook add in. It does not open instead of tasks, as shown in clip. I cannont find it anywhere in outlook.
please go to Outlook's Options -> Add-ins and at the bottom of this window, you'll see a drop-down menu saying "COM Add-ins" and a "Go" button next to it. Click on the "Go" button and you'll see a list of your add-ins with check boxes. Click the check box next to OutlookTodoist and save the changes.
If you don't see it on the list, please go to the Add/Remove Programs menu in your system's Control Panel and see if you can find "OutlookTodoist" on this list. If not, please try to reinstall it by right-clicking on the installer and choosing "Run as Administrator" (or "Run as..." in Windows XP).
