I've been having a problem with my printers for the last few days now...

For some reason one of the options that enabled the users to print to their mail boxes (where all documents are stored before actually printing) is "unticking" itself.
I'm the only Domain Admin that has access to any of this and I know it's not Me, Myself or I doing it...

Has anyone come across this before and if so how the heck do you stop it happening!
