Hi, I have spent the last few hour looking through all the post on this list to do with OWA but was unable to find an answer that solves the problem I currently have. I have two sites, both have ISA installed on them, and one (the Remote site) has an exchange server published with OWA. The local site has ISA and that is used to surf the web. Until yesterday everything worked fine. Then I ticked the box that forces authentication on all outgoing web requests. The Outgoing web requests are set to use Integrated and basic authentication. All the machines in the local site have IE5.5 or 6 installed so people continued to surf and did not notice the change. The problem I have is when I connect to the published OWA server I have logon failures. It asks me as normal for my username and password, and draws half the OWA web page and then will ask me again for my password, but this time it will not accept it. Sometimes I can see the titles of items in my inbox, but can not open them, I am just prompted for my password again and end up with an Access Denied message. Anyone got any ideas? It would seem to be a problem with the outgoing ISA serves config, but I can't work it out. Thanks Stephen.
