Extension Attribute as Password for Exchange ActiveSync in Configuration Profile

New Contributor III

Is anyone aware of a way to use a stored password for ActiveSync profiles? It would be great for our school if we could just store their password (which only the teachers know) in an Extension Attribute and then populate them when the profile gets sent out, rather than have to touch every device. I'm able to populate the rest of the fields with variables, but can't make the password field stick.
