Shoffman,

It may be possible to have each user save the containing folder as a favorite. Public folders, when right clicked, have an option to save as a favorite. This can be done with your public calendar. (Please test before allowing your employees to perform these tasks)

Have one of your users follow your steps "open Outlook, click Calendar, then select public calendars in public folders, then they have to click in the public calendar." Have them save this calendar to favorites. They should be able to then only perfomr the last section go to Actions>>View Group Schedules>>Select All Employees>>Select Open.

Please note: since my instance has public folders with one standard view please test this before implementing to our staff.

Hope this helps
