I am trying to build a web services application and I seem to have an issue with configuring web services. I have configured Exchange and IIS with an EWS virtual directory. I am able to access the services.wsdl file, but I cannot seem to use the exchange.asmx file. For example, when I use: https://myserver/ews/Services.wsdl - I see the file. But when I use: https://myserver/ews/Exchange.asmx?wsdl - I get a 404 error. Exchange.asmx has all the same permissions as Services.wsdl. When I attempt to make a web service call, I get the same error. Thanks, Mike
