Your admins are idiots. Mine has not had the "never" option ever since I sync'd up to Exchange and loaded the security profile they forced on me.

Doesn't sound like "admins" is the right word.
Go to Exchange System Manager > Global Settings > Mobile Services (right click, properties) then click the Device Security button. They can even add you as an exemption if they want, but all the settings are in here. (exchange 2003)
