How to open Exchange 2010 Shared Calendar?

Solution 1:

To expand upon Ubuntuser's comment that helped me along the path:

  1. Set up evolution-ews and get your inbox functional. Make sure you're online, and syncing.
  2. On the Mail view, right click your exchange account, select "Subscribe to folder of other EWS user."
  3. Type in the name of the account you want, and choose Calendar from the dropdown.

It will silently add itself to the calendar view under your exchange account.
