CDO property tag for Billing Info?

[Bingo]

I was using Outlook Object in my VB app. I kept the
original EntryID for each email in it's
BillingInformation field. Now I'm switching to CDO but I
cannot find this field any more. What's the property tag
for this field? CDO does have a property of
CdoPR_ORIGINAL_ENTRYID but I'm not sure if this is the
field I can keep my data in. Thanks.

See http://www.cdolive.com/cdo10.htm
On the Extended MAPI level, it is ({00062008-0000-0000-C000-000000000046},
0x8535, PT_STRING8)
Look at the messages using MdbView or OutlookSpy to see what other
properties are available.

What about CdoPR_ORIGINAL_ENTRYID? I got error when I
tried to write and read to this field. Thanks.
