[Blind-sysadmins] Accessing shared calendars in Outlook 2016

Hi all, I just got access to a shared calendar in Office 2016, and while I can find it via the F6 toggle, I cannot seem to activate it by doing that. Right clicking on it and saying show calendar, doesn't seem to let me access it via the keyboard either; the show calendar option seemingly remains unchecked. A, I doing something incorrectly here? Thanks.
