This article was previously published under Q189999 SYMPTOMS
When a recipient of message that has been sent as a BCC to other recipients
embeds this message in another message, the BCC recipients become visible
in the embedded message. This only occurs with the Windows 3.x or Macintosh
clients. 32-bit Windows clients do not display this behavior.
CAUSE
Attachments (including embedded messages) do not have the delivered flag
set during a CopyTo operation. Because BCC display is based on whether the
message has been delivered, this causes the BCC recipients to be shown at
all times. Outlook 32-bit Windows clients are using a fast transfer
mechanism that strips off the BCCs during the copy (instead of a CopyTo as
the Windows 3.x and Macintosh clients are using). This explains the
discrepancy between the client behaviors.
