Thanks to the help I've received from David Bergeron and Wayne Robshaw, I've
managed to resolve this issue. It seems to be a bug introduced into the
Pocket PC 2003 version of MAPI. So others who have the same problem can
find a solution, I've included the workaround here. The stream for the body
of the message is not being autosized properly, and needs to be sized to the
size of the body plus a little bit extra before streaming the text into it,
as demonstrated here:
ULARGE_INTEGER uiSize;
uiSize.QuadPart = ((MessageBody.GetLength()) * 2) + 1000;
pStream->SetSize(uiSize);
Then you can stream the text into the message body using the write command.
This problem only occurs under 2003, but the above fix works OK for both
2002 and 2003.
My thanks go to David who had discovered the workaround, and the additional
help provided by Wayne.
