I’ve been skimming the book 6 Microsoft Office Business Applications for Office SharePoint Server 2007.
There is an inspiring chapter about a CRM app, that uses outlook for forms generator and offline functionality. Sharepoint is used for workflow engine and doclib and MS CRM as backend.
Some slides from SalesOutlook CRM gives a little similar idea, but the book gives you the complete idea.
But the book Programming Microsoft Office Business Applications (Pro – Developer) even provides two online chapters:
- Chapter 4: Integrating Web Services into Your Office Business Applications
- Chapter 7: Managing Complex Business Processes with Custom SharePoint Workflow
More samples available on Office Business Applications Developer Center.
Finally there is the OBA homepage to explore.
