With export to EPS it's working fine with Outlook 2011.
But transparency is not preserved with EPS...
so not usable for me, too.

I'm trying different preferences for exporting SVG.
Opening exported files in Illustrator and Scribus is showing different results in both programs always.
Sometimes boxes are only in one colour, and shadows are not viewable always.

I can view SVGs exported from Omnigraffle within Firefox - but I cannot use them with Outlook or Keynote.
