The Calibre documentation still lists OEB as an output type, but I agree that the GUI does not show it. I suggest converting the HTML to ePub using Calibre, then rename the .epub to .zip and unzip it. An ePub is just a zip container with HTML/XML plus an .opf file which you can import into MobiPocket Creator, it is essentially OEB 2.0 vs the 1.1 typically used as input by MobiPocket.
