I'm using Word 2010 on a Win 7 machine. I'm having problems with mail merge in that when the merge is complete and I click on "OK" once the mail dialog has been completed, nothing happens. My e-mail client does not open up, nor do I see any messages in the outbox. This used to work just fine with Windows Live Mail and Word 2007. I then installed Word 2010 and it does not work now. Any suggestions from anybody? Any assistance would be MUCH appreciated. Microsoft is no help - impossible to contact.
