Erik Sojka (MVP) shared these words of wisdom:
It will differ depending on if you're using 2003 or the 2007
beta, but File "Save As, and File | Send To..."
will give some options on saving ON content for people who
don't have ON.
As the combination of ON 2007 and Outlook is not yet working the way
(one always has to remember that it's stil Beta <!>), one may work
around the problems by just using Outlook Express.
If the latter is set as the standard mail-handler, sending ON 2007
stuff as PDF-attachment works fine.
And if one has set op Outlook as well as OE for IMAP the proper way,
sent-mail will even land in the same folder and can be used from both
mail-handlers.
