I can not delete the duplicate mailbox as it does not show any properties or allow to delete through the System Manager. Anyone know how to delete this or change the name? I show 2 of the System boxes shown below in the error. The Teknote describing the error is below this.
An ambiguous SMTP proxy SystemMailbox{E8CCB36D-7F07-468E-95CE-3B164E7572ED} was found on 0x2 mailboxes in the DS. The store cannot map this SMTP proxy to a unique Mailbox GUID.

Message: An ambiguous SMTP proxy was found on {number} mailboxes in the DS. The store cannot map this SMTP proxy to a unique Mailbox GUID.
Explanation
More than one mailbox is using the same proxy address. The store cannot map the proxy address to a mailbox GUID because of the redundancy.
User Action
Change SMTP proxy address of one of the mailboxes, so that each mailbox has a unique address.
