Remarks 
The message
store computes the PR_DISPLAY_BCC property on message objects using the IMessage::ModifyRecipients method. The message store
also maintains the property so that it always reflects the last saved state of
a message. The value is synchronized at the time of every call to the IMAPIProp::SaveChanges method. 
If a message
has no blind carbon copy recipients, the message store should respond to an IMAPIProp::GetProps call with a return value of
S_OK and an empty string for PR_DISPLAY_BCC. 
Because of
the possible need for localization, MAPI provides some guidelines for blind
carbon copy recipient names:
    All names should be able to be
localized.
    The semicolon should be the
character that is used to separate names in the PR_DISPLAY_BCC property. 
    Clients must translate the
semicolon encountered in the PR_DISPLAY_BCC property to a localized separator
character before making the property information visible in the user interface.
Note  Semicolons
cannot be used within recipient names in MAPI messaging.
