Keeping Mail & iCal open

Question

Is there any way to prevent an app. from being quit without first entering a password? I want to keep Mail & iCal open at all times, but my colleague keeps quitting rather than hiding them.

Hello Andy.
No there isn't and the best way to resolve this situation is by creating a computer login account for your colleague with or without admin privileges as you see fit.
OS X was designed for multiple computer users in this way with each user/login account having their own Home folder/directory to store their data only and protecting it from other users. Each user's Home folder/directory includes a Shared folder to place documents, etc. that need to be shared between multiple user login accounts.
Each user/login account can have their own Desktop wallpaper, screen saver, settings, etc. to make it seem as if the Mac is their own and your colleague can quit Mail and iCal after being opened to his/her content without affecting anything already open in your login account.
Enabling Fast User Switching makes the process of switching between user login accounts a fast and easy process which doesn't require quitting any applications in a user's login account when switching to another account.
