Exchnge ’03 Email Address tab Missing

Platform: – SBS’03, Exchange’03, & Workstation on XP Pro.
Problem: – One of the 3 users on this small network has one primary email address and two other “additional SMTP email addresses” set up in the profile. It is operating fine.
– When I went in to remove the additional SMTP email addresses in AD and Server Mgt. User Profile, the “email address” tab is missing.
– The other three exchange tabs are present.

Troubleshooting done: – I’ve restarted the services.
– Copied the user and created a new user. The new user’s profile has the email address tab.
– One person suggested that the “profile” is currupt. However, I don’t know how to rebuild it without loosing the 41,000 emails in the user’s folder.
