Just a short note on how to get Exchange Web Service (EWS) URL when “ask your Exchange administrator” is not an option 🙂
Method 1 – execute the following command in Exchange Management Shell:
Get-WebServicesVirtualDirectory |Select name, *url* | fl
Method 2 – Using “Test E-mail Auto Configuration” which available in Outlook client starting from Outlook 2007. Just right click on Outlook icon in tray holding Ctrl key and select “Test E-mail Auto Configuration” option, type in email address hosted on your Exchange server and Click “Test” – once you get output check “Availability Service URL” value – it contains you Exchange Server EWS URL.
