dispidHeaderItem

Quick Info

Exposed on:Message objects
Created by:Outlook
Accessed by:Outlook and solution providers

Remarks

To retrieve the value of this property, first use IMAPIProp::GetIDsFromNames to obtain the property tag, and then specify this property tag in IMAPIProp::GetProps to get the value. When calling IMAPIProp::GetIDsFromNames, specify the following values for the MAPINAMEID structure pointed at by the input parameter lppPropNames:

lpGuid:PSETID_Common
ulKind:MNID_ID
Kind.lID:dispidHeaderItem

This property returns a non-zero value when only the header of the message has been downloaded. It returns zero when both the header and the body have been downloaded.

If Outlook is configured to connect to an IMAP mail server, use IProxyStoreObject. For more information, see How to: Access a Message on an IMAP Store Without Downloading the Entire Message.
