When I try to send an internal email to a specific user, it is redirected to the BadMail folder with the following message:
A configuration error in the recipient's e-mail system prevented
delivery of this message. Two recipients are configured with the same
e-mail address. Contact your administrator.
It also logs an event Source: MSExchangeIS ID: 9514 which tells me that Microsoft System Attendant and Public Folder Store have the same proxy.
My problem is that I do not know how to remove the email addresses from these 2 objects. They do not appear in Active Directory Users and Computers, and Exchange System Manager does not give me an option to modify email addresses.
Thanks for your help.
