The information in the Bcc field of messages is missing after you move mailboxes from Exchange 5.5 to Exchange 2000 (831918)

CAUSE

This problem may occur if the mailbox contains messages that the users sent to themselves and to other recipients. Additionally, both of the following conditions must be present:

The To field of the message contains the e-mail address of the user who sent the message.
The Bcc field of the message contains the e-mail address of other recipients.

In this situation, Exchange Server 5.5 incorrectly processes the information that is contained in the Bcc field of messages that are stored in your users' Sent Items folders when you move the mailboxes.
