CRM 2013 Campaign Activity Mail-Merge tracking problem

Hello,

I use CRM 2013 on-premises and Office 2013. I create marketing campaign with an Email Mail-Merge campaign activity from Outlook. When I distribute campaign activity, correctly, Word is launched. I then go through all the steps in Word to edit a document (it is merged correctly). When the last step "Send emails.." is done, I do not get a prompt to track/create activities in CRM. That dialog simply does not appear. So, no distributed activities are created for that campaign. CRM-Outlook configuration wizard on a local machine is synchronised with a correct CRM organisation. Any ideas how to solve this problem?

Thanks for any information.
