Workaround for Windows 10: Not clean integration, but works.
Open the 'Calendar' windows store app that comes with the Windows 10 install. Add the accounts with the calendars you want. (I turned off the e-mail sync in the settings, already getting the e-mails in Outlook)
Grab the side of the Calendar app and shrink its width as much as possible. The view will change to 'Agenda' which will show a similar view as the To-Do Bar in Outlook, but with all of the calendars overlapping.
I then snapped Outlook, and the Calendar app side by side, and shrunk the Calendar app as much as possible. I then closed the To-Do Bar in Outlook to save space.
Again, not clean, but works for me! (until Microsoft figures out they can add the same feature to Outlook)
