GDay<br><br>We have 20 POP mail accounts hosted at an ISP.<br>All clients can browse via our internal MS Proxy.<br>No clients can access their personal POP mail boxes from Outlook.<br><br>In the past we haven't had to configure proxy to do anything 'out of the ordinary' where we have set up similar arrangments at other sites.<br><br>We are using an ISP we don't usually deal with at our clients request. They don't give MS Proxy support, but say there should be no reason why we can't connect to the boxes.<br><br>Please help ASAP, or I am closing the POP accounts and installing Exchange.......
