Hi, we're currently running Outlook 2003 SP3 with Exchange 2003 SP2.

Symptom: User_A sends a meeting invite to User_B & User_C. When User_B or
User_C accepted the meeting invite, the Meeting Invite automatically change
the attendees names from "Display Name" to "Alias name".

This problem happens on some of our users, not all.

Deleted the Outlook NKF file but still happens on some users.

Any other suggestion that i can try?

Regards,
Patrick Lee
