How do I integrate SharePoint Calendar with Lotus Notes?

Asked By 20 points N/A Posted on -

I have been using Lotus Notes as my primary user-interface software as it is very easy to use and I have grown quite familiar with it. However, now that I have started to use SharePoint 2010, I have no idea how to integrate my Calendar with Lotus Notes.

I want these two tools to be linked together in such a way that whenever I add something in my SharePoint Calendar, the same entry will automatically appear in my Lotus Notes Calendar as well.

Please help me out because I need this to help me organize my stuff. I would really appreciate it if you can show me how to do this through a short video tutorial. Thank you very much, and cheers!
