Hi, I was trying to configure my test Exchange 2003 server to not use anonymous access for owa and when I unchecked anonymous access, clicked integrated windows authentication and clicked ok and then was prompted whether to change the child nodes which were exadmin, exchange, Microsoft server-ActiveSync, OMA & Public to which I selected all, clicked ok again and then was again prompted for authflags property for these same child nodes again, to which I again selected all and clicked ok. Now I cannot login via our OWA server to my test account on that exchange server. I tried to check Anonymous access again and clicked ok all the way down but it still doesn't work. Do you have to leave anonymous access in place for owa to work or can this be changed to use windows integrated authentication? Thanks a lot in advance for any help you can give me. Best Regards, Fred Towery

Hi Fred , What's error message you get when trying to access OWA? Please follow the KB article that provide by Shafaquat to reset OWA virtual directories then test to see if the issue persists.
