Like all non-Office formats, you need a translator for this so Access can convert it.
Forward your question to Microsoft to determine if they have a plug-in that exposes some elements, properties, and methods so you can perform the required conversion. (I'm not advising you to hold your breath on that.)
Failing that, see if they have plans for an output formatter similar to the .PDF formatter, which would allow you to do an OutputTo operation.
If that doesn't work, look for 3rd party software that is available as a DLL or other type of library and that offers "hooks" under Common Object Model standards.
I looked up some stuff online before answering this but didn't see much that appears useful. But I'll admit it was a cursory search.
