When moved to Server I got an error of Forbidden with Service resolving/working properly (i.e WSDL file works fine). After adding Server Version - Dim service As ExchangeService = New ExchangeService(ExchangeVersion.Exchange2010_SP1) or Dim service As ExchangeService = New ExchangeService(ExchangeVersion.Exchange2010) or Dim service As ExchangeService = New ExchangeService(ExchangeVersion.Exchange2007) I get an Exception of type ServiceRequestException - "exchange server doesn't support the requested version" Outlook Exchange WebMail has an ABOUT Description of Version - "Mailbox server Microsoft Exchange version: 8.3.83.0" S/MIME control: not installed Exchange Client Access server .NET Framework version: 2.0.50727.3625 Client Access server operating system version: Microsoft Windows NT 5.2.3790 Service Pack 2 Client Access server operating system language: en-US Microsoft Exchange Client Access server version: 8.3.83.0 This below link suggets that we have to use "Microsoft Exchange Server 2007 SP3 8.3.83.0 or higher"but there is no Overload in New ExchangeService(ExchangeVersion. --------------- ) http://www.msoutlook.info/question/277 Kindly let me know if some other configuration has to be done or any other way for doing this Other Links W/O Solution: http://answers.microsoft.com/en-us/office/forum/office_2010-outlook/office-outlook-web-access-and-outlook-2010/55e29d2b-8588-47e1-87ae-3909021a5cc8
