Environment is Windows 2003 domain based. XP Pro workstations.
On only one user, when she receives rejected emails back to her inbox, appear one day before the correct time/date. If this same user receives email from anywhere else...it shows up in the inbox correctly.
When the SAME rejected email notification is displayed on her account in OWA...its time/date are correct.
Also, I tried her email account on another domain workstation...and the problem occured there as well.
