We have implemented in our public folders a booking room system

Do you know how to retrieve with Oulook the name of a user who has
inserted a reservation in this public calendar ?

View the calendar in a table view like By Category. Right-click the header
bar and choose Field Chooser. Select "All Appointment Fields" from the
drop-down and add the Organizer field to the header bar. That should show
you who created the entry.
