I'm wondering if there is an easy way to disable OWA on 500+ users without going to the properties of each user. It seems that the value must be stored in the Exchange database somewhere, but I have no idea where to look or how to set it. I'd be happy with disabling everyone and then re-enabling the 7-10 people that needed it.
Part two-- how do I set the default for new users to have no OWA access? Thanks much in advance!
