When working in outlook with the CRM plug-in, the button MAIL MERGE doesn't work, we need to do it in Outlook via de CRM plug-inn because then the document wil be saved into CRM.
It looks like it stops working after e re-install of the plug-in or a repair.
I try to re-install the CRM plug-in (incl. removing all registry entry)
I try a re-install of Office 2010
