I am running outlook 2003 and exchange 2007. My users are using outlook anywhere. when recently when they are home and try to access someone's calendar they have permissions to it prompts them for their creditnetials. I have confirmed the log in protocol is set to basic on both the client and the server. the url is correct on both sides. its a verisign ssl cert. not sure what cause this or how to fix it.

Check if this is checked under IIS on the Exchange server. Under Autodiscover properties> Directory Security> Authentication Methods> check "Integrated Windows Authentication".
