We have a Shared Drive here in my office (training department for a local
healthcare system.) I have a Room Reservation calendar on the Shared Drive
for everyone to view. When opened, a prompt "Do you want to open as
Read-only" pops up. When I open it, I tell it "No" so that I can make
changes. However, I do not want anyone else in the department to be able to
make changes.

Our Computer Instructor and I tried figuring out now to protect it to where
I am the only one who can make changes, even with it being on the Shared
Drive, but are having trouble. Can anyone help?
