I keep getting asked if our free postcode lookup add-on for Dynamics CRM is available for CRM 4.0
The answer is yes it is – the package and source code is on the MSDN Code Gallery.
It uses the PostcodeAnywhere web service to lookup and deliver addresses.
This was developed and tested on Windows 2003/IIS6. It does work on Windows 2008/II7 but instead of importing the Virtual Directory, add a new Application to the site and give it the same Alias Name and Location as in the instructions and configure the application to use the [Classic .NET AppPool] Application Pool
