PidTagDisplayCc Canonical Property

Last modified: July 23, 2011

Applies to: Outlook

Contains an ASCII list of the display names of any carbon copy (CC) message recipients, separated by semicolons (;).

Associated properties:




Data type:




The message store computes these properties on message objects by using the IMessage::ModifyRecipients method. The message store also maintains these properties so that it always reflects the last saved state of a message. The value is synchronized at the time of every call to IMAPIProp::SaveChanges.

If a message has no 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 these properties.

Because of the possible need for localization, MAPI provides these guidelines for all 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 (PidTagDisplayBcc), PR_DISPLAY_CC, and PR_DISPLAY_TO (PidTagDisplayTo) properties. Semicolons are not permitted within recipient names in MAPI.

  • Clients should translate each semicolon encountered in this property to a localized separator character before making the property information visible in the user interface.

  • When forwarding messages, clients do not need to translate the separator characters on the carbon copy recipient line.
