From the developer:
Many CRM vendors claim that they are providing Microsoft® Outlook® integration with their CRM solution but customers have to bear the additional charges. Most of the open source CRM projects are not exceptional to this trend. They provide CRM software as free and open source but when it comes to Microsoft® Outlook® integration, it is closed source.
