BAE Australia is a WADM user with Windchill 8. The WADM won't give you any CRM type capability. Managing emails in Windchill is something many of our projects would like to do. Using Arbortext's xml block of reusable text is one option but I wouldn't adopt Arbortext just to manage emails. The Desktop Integration addon used to place a non functioning Windchill button in outlook, with Windchill 7, but this issue has been fixed in Windchill 8. It only worked with MS Word, Excel and Powerpoint. You could try integrating one of the open source CRM tools, like SugarCRM or TigerCRM, with Windchill.
