Hi, I am currently installing exchange 2003 for a school. The teachers should be able to use the Outlook fat client, but the students should only be allowed to use OWA. I know it is possible to disable Outlook fat usage on a user level (this is being done in the hosted exchange solution) but I can't find any information about it. Does someone know how to disable Outlook fat client usage on a user level? Kind regards, Dennis Appelboom XB
