It gives the error "There was a problem connecting to this app". Just doing a quick Google search it looks like a widespread problem. I have a ticket open with MS but no answers yet.

It does work in the Outlook online app.

    Reset the Office cache, it should fix the problem:

    1. Close Outlook
    2. Rename or Remove these two folders: %LOCALAPPDATA%\Microsoft\Office\16.0\wef %userprofile%\AppData\Local\Microsoft\Outlook\HubAppFileCache

    Re-open Outlook and click the "To-Do" shortcut, and it should open without issue.
