You should not have to touch every end user workstation to make such a 
simple config change.

Windows, Outlook, and Active Directory can be controlled via scripting. 
(Yes, I'm going out on a limb and guessing you're in the 90% of 
businesses that run all three for end users and their workstations.)

OS X, Mail, and Entourage can also be remotely controlled and scripted.

I'm not familiar with other mail clients to speak about their 
capabilities. Though, obviously, nix-based setups are typically 
scriptable.

It has been a long time since I've had to directly support end users 
and their workstations, so you'll have to do your own homework on how 
to do this. I only know you can do it.


Aside: Anytime you, as a sysadmin, consider touching every end user 
workstation something has gone very, very wrong.

Either you need to bone-up on administration best practice or get/learn 
better tools or both.

I hope this helps.
