Hi, I was wondering if there is an Exchange Server that's public so I can test the EWS API in C#, rather than through VPN to a private network (I'm having problems with my router & VPN). Thank you!

I'm not ware of a public Exchange server for testing. But if you have problems with establishing a VPN connection, does Outlook Anywhere work?If so, EWS is (or should be) enabled for access from the Internet. You can see the URI for EWS from Outlook:Ctrl+Right click the Outlook icon in the Notification Area, and select Test E-mail AutoConfigurationhttp://www.msexchange.org/articles_tutorials/exchange-server-2007/management-administration/configuring-outlook-2007-exchange-server-2007.html Then you should see something like:https://webmail.domain.com/ews/Exchange.asmx You could also download the Exchange 2010 Web Services SDKhttp://msdn.microsoft.com/en-us/exchange/default.aspxBy default the Autodiscover Sample application installs here (which will provide the same information):C:\Program Files (x86)\Microsoft\Exchange Server 2010\Web Services SDK November 2009\Samples\Autodiscover(The application in itself is quite handy, and the code is easily integrated into other programming projects.)MCTS: Messaging | MCSE: S+M | Small Business Specialist

Hi Jon-Alfred Smith, Thanks for the links :D May I ask, Do I need a VPN access to access an email account to an Exchange Server 2003 using EWS, from a website like 'https://www.entermo.com/exchange' ? Now I'm a bit confused. It seems that I can use EWS without VPN-ing into my company's network. My ultimate goal is to write a program to automatically extract the latest emails from an email account to retrieve some attachments and store it in a database. Thank you for your reply!

Exchange 2003 does not support Exchange Web Services (EWS).Any way to use EWS against Exchange 2003? Does proxying do translation from EWS->WebDAV?http://social.technet.microsoft.com/Forums/en-US/exchangesvrdevelopment/thread/73a3083c-87f5-45a2-9468-c57b2266d56c You need to access an Exchange 2007 or 2010 server. If Outlook Anywhere (OA) is enabled on theses servers, access to EWS from the Internet is enabled as well. That is if OA is configured properly. OA uses EWS for Availability and the Offline Address Book. Mac OS X 10.6 Snow Leopard Mail, iCal and Address Book use only EWS, so does the latest Microsoft Exchange client on the Mac: Entourage 2008 v.13. Neither OA nor SL Mail or Entourage require a VPN connection to connect to an Exchange server from the Internet. They connect directly through port 443.MCTS: Messaging | MCSE: S+M | Small Business Specialist

Thanks for your help! Looks like I'll have to be using WebDAV then. :)

Often WebDAV is accessible from the Internet as well (without VPN). In Exchange 2007 WebDAV is still supported, but discouraged. In Exchange 2010 it's gone.MCTS: Messaging | MCSE: S+M | Small Business Specialist
