When you try to configure Microsoft Dynamics CRM for Microsoft Office Outlook, you receive the following error message:
"The server address (URL) is not valid"
The URL you provided is either not valid or is not working to access Microsoft Dynamics CRM.
To verify that the URL is valid and can successfully access Microsoft Dynamics CRM, try using the exact same URL to access CRM via your web browser. If you are unable to access your CRM organization via your web browser, CRM for Outlook will not be able to access either. If you are attempting to connect to a CRM Online organization, try choosing the CRM Online option instead of typing a URL in the Microsoft Dynamics CRM for Outlook Configuration Wizard.
