See below- when I open our Conference room calendar in Outlook 2016, instead of showing me what's on the Room calendar, it simply copies everything over from my default calendar. If I add events to the Room calendar, it adds them to the default calendar instead.
Notable- this is the only computer running Office 2016, every other computer in the office is running Office 2013.
EDIT: Also, the default account is shared by 4 users since it is our CEO's and his executive assistants use his account. If I add the room calendar, all the other users can see it just fine but this still happens on the Office 2016 installation. The same thing happens if I add it from one of the other users' installations, it shows up fine for them but I still have this issue.
