COM add-in can't update sent message MAPI properties in Outlook XP.

[Alan]

Hello,

I've written a COM add-in in VB .NETwhich adds tracking info (message
delivered/read times) from external messages to the appropriate sent
message.

The add-in works fine in Outlook 2003. However, in Outlook XP/2002, it
only works if the sent message has not been opened by the sender in
Outlook until after the add-in has updated the tracking info. It's as
if the sent message becomes read-only once the sender opens it from
their Sent Items folder.

Anyone seen similar behaviour before please?

The setup is Outlook XP/2002 or Outlook 2003 against an Exchange 2003
server (MAPI profile, online mode). I'm using Redemption RDO but I
don't think it's related. I'm adding the Tracking tab to the sent
message, then updating the PR_RECIPIENT_TRACKSTATUS_TIME_READ,
PR_RECIPIENT_TRACKSTATUS_READ, TrackingStatus and TrackingStatusTime
MAPI properties, as well as changing the envelope icon.

Thanks,

- Alan.
