Access Outlook from Rails App?

Hi Folks,

is there a way to access the Outlook-Folders from a visitor to a hosted
Rails Application? For example get the emails the visitor has in his
Outlook and show them on the website. I read about “WIN32OLE” and
wondered if it is also possible to use it via the web in a Rails App.

Would be nice to hear some hints on that because I am not so much into
networking.
