How to display all calendar in the location

[Lisa]

Hi,

I recently created a few calendars in public folder for the conference room
for people to book. People want to have all conference room to be displayed
in their location drop down menu when they create a new meeting instead go to
the public folder every time. How can I make that happen? Currently there is
no any conference room displayed.

Any help will be appreciated!

Thanks in advance!
