Hi, I have Exchange 2007 on Server 2008. OWA works for most users, however a few user get "Page cannot be opened" error by using IE, Firefox. What could be the problem? I think it's something to do with the browser, but don't know what it is. Please advice! Thanks, Gracegrace

Does the problem follow the user to another machine? Flush the temporary Internet files in the browser - that will usually correct many of the problems. Simon.Simon Butler, Exchange MVP Blog | Exchange Resources
