Reto, I have been able to replicated the scenario where a modified instance of a recurring appointment disappears in Outlook 2013 and SmarterMail.  I have added it to our bugs list.  We are actively working to resolve several ActiveSync issues.

To add to what Robert has said.  Please see this topic where we discuss in a little more detail what were working on: http://portal.smartertools.com/community/a703/new-microsoft-outlook-for-mac-from-office365.aspx
