Windows 7 - A question about PR_CONVERSATION_INDEX

Asked By Devesh Sarwate on 13-Jan-09 02:37 AM
I was doing some research on PR_CONVERSATION_INDEX to use it to identify
copies of same message when I came across Dmityr's answer to a question
about this property.
In the answer below he has written that ConversationIndex property is broken
in all versions of outlook except 2003.

ConversationIndex property - the first 22 bytes are the same for all
messages in the thread. Each message adds 5 bytes to the conversation index
of its parent message.
Note however that ConversationIndex property is broken in all versions of
Outlook except 2003 - OOM returns binary data in the string wirth the length
of the data in the first 2(?) bytes. Outlook 2003 finally fixed that and
returns a hex string, the same way it does that for other PT_BINARY MAPI
properties (such as PR_ENTRYID).

Does this only relate to fetching this property using Outlook Object Model?
Is there a problem using this property through extended MAPI with code
running against Exchange 2000/2003 etc?

Also if some Outlook versions had problems fetching this property, were
these versions atleast setting this property properly on outgoing messages?


Thanks
Devesh

Yes, that only applies to the Outlook Object Model. Outlook 2003 and 2007
work just fine. MAPI is also fine in all versions.
