Configuring the List Component in SharePoint Online

The Microsoft Dynamics CRM 2011 List Component adds functionality to SharePoint which enables Document Management capabilities in Microsoft Dynamics CRM. In order to deploy the List Component Solution the following modifications to SharePoint are required:

• Run the following command in the SharePoint Management Console for a specific Web application: AllowHtcExtn.ps1 .
• Alternatively, set the Browser File Handling to Permissive to allow automatic execution of Web content. Only a farm administrator can change the Browser File Handling settings.
