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?
