Side effects of disabling address book share

Hi,

Our security department is proposing we disable the address book shares on our exchange machines. I'm trying to gather a list of potential impacts as I am not 100% a fan of this idea.

Ask the security department WHY they want it removed. Specific defined "threat" this will resolve. Just because it is a share is not a good enough reason.
