I have a shared calendar on my outlook for Mac (not Outlook 2016), but I need to open and sync that cal to my ical.
Open Apple Calendar. Select Calendar > Preferences.
Go to Accounts, and click the + icon on the bottom left.
Select Exchange, and enter your credentials. 
That's it! Calendar will take care of the rest!
