Menubar app for MacOS that syncs with Outlook

At work we are forced to use outlook with two step authentication via Duo authentication app. So I can not use Fantastical or Mac Calendar. Outlook being the one app for calendar and mail it is hard when I want to see both email and calendar. Is there any app that works with menu bar so I can check quickly my calendar but also works with Duo?

I don’t use Outlook on the Mac, but on Windows, if you right click on Calendar on the bottom left, you can open it in a new Window.

The other option may be that under View, can you open a To Do sidebar (or Shift + CMD + ] )on the right of your Inbox and swap it to Calendar?
