How can I disable new accounts in GMS? I am removing the ones with Win
Mobile so to switch them to Mobility.

As it is now, I can delete the account but the app is installed on the
device so they are prompted for their password and GMS re-creates their
account and they are back in.

I have to keep the GMS up for Palm users so I can't just take the server
down but I want to lock out any users that have active sync devices.
