Outlook 2007 error sending to local and exchange distribution lists simultaneously

I am running Exchange 2003 and have a user who is running outlook 2007.

She has a distribution list in her contacts that include exchange distribution lists as well as distribution lists that she created in her contacts.  When she sends a message to this distribution list, all lists that are in her contacts come back undeliverable with an unknown e-mail address.

It worked fine in Outlook 2003.

I verified that the local distribution lists work fine when sent to by themselves.  Has anyone run across this before?

You might need to recreate the list using a different name.  Keep it simple.  Outlook remembers distribution list names.
While we seem to trust microsoft for their distribution list migration, sometimes there are some burps with it.  I strongly suggest you delete the distribution list and then readd the users in a brand new distribution list in Outlook 2007.  Easiest process will be exporting that as a comma separated value file.  Open the file containing addresses, copy them and paste them in the new distribution list.  
I wish There was a button that says "Clean imported distribution list ..."
Hope this helps you

I created a brand new distribution list and added the users and other distribution lists.  Same issue.  The local distribution lists show up as users with unknown addresses when you expand the group on the "To" line.

The local distribution list works fine when sent to it solely.

It's when you send it as part of another distribution list that includes exchange distribution lists that causes it to wig out.

I used a different name when I created it.  I used "Test"
