I have configured Exchange 2007 on an SBS 2008 server. Brand new, factory fresh image. All of my network workstations are configured and connected to Exchange 2007 through Outlook 2007. However, from time to time each user receives pop-up windows asking if it's okay to authenticate to http://remote.xxxxx.xxxx
-- but I'm not sure why? I don't know how to turn this off or stop it from happening? Seems the digging I've done online has something to do with autodiscovery in Outlook 2007 and how it connects to Exchange 2007. Any help out there?
