PGV - Enforce a disable of specific Exchange Protocols?

Hi guys,

     Our Exchange team has requested that we disable certain Exchange Protocols (IMAP4, POP3) on a new Provision.

My first thought was adding an Property Generation & Validation rule to our Exchange Provisioning policy.

To enforce the ARS attributes:

edsva-MsExch-ProtocolSettings-IMAP4-Enable

edsva-MsExch-ProtocolSettings-POP3-Enable

And set the default rule as:  FALSE

However, this doesn't appear to work (unless I am setting the attribute value incorrectly).

Any thoughts/comments on this?

Thanks again everyone!

James
