Hi,
I might be able to provide half of the solution.
I can show you how to get the active X working with Matlab and Outlook but I have no idea which command you need to export calendar items. You should be able to find the needed method on the msdn website of microsoft.
% Active X Connection
h= actxserver('outlook.Application');
% Do something (f.ex. create email)
h2 = h.CreateItem('olMail')
