Administering an Exchange 2003SBS server with 15 AD users, all with email addresses. One user needs to be removed from Exchange but kept as an AD user. So deleted her mailbox via AD USers. Then set up her email as a POP/SMTP account pulling mail directly from the ISP server. External mail comes in great, but anytime an internal user tries to mail her, it bounces. I did add the domain name into the "Forward all mail with unresolved recipients" box in the Default SMTP Virtual Server" properties, but still bouncing with this:
This is the mail system at host smtp4.[isp].net.
I'm sorry to have to inform you that your message could not be delivered to one or more recipients. It's attached below.
For further assistance, please send mail to postmaster.

Wonder if it could be connected with the Global Address List. Know little about this, but understand it populates automatically from AD. The user MARION does have an entry in the GAL but there doesn't seem to be a way of deleting it. I think if we could, this might resolve the issue. Thought once I'd removed her mailbox from AD, her entry would disappear from the GAL but it hasn't.
