There is no supported approach for that. There might be a change when the
final version of Outlook 2010 gets released but due to the amount of changes
in the profile configuration, making Outlook 2010 mail profiles fully
forwards compatible with Outlook 2003 and Outlook 2007 might not be
possible. Even though your mail profile seems to be working after the
downgrade, there are still some keys "under the hood" that are missing and
could cause later mail profile corruption or other errors. That is also the
reason why you should not use BETA software on a production machine against
production data.
