When does Outlook shows paper clip icon in folder view?

[George Wang]

I have several messages with one embedded attachment each (all created
within Outlook, not as described in Q218356). The weird thing is that
only some of these messages show the paper clip icon in the folder
view, but others don't.

I examined the properties of these messages, all having PR_HASATTACH
set to 1, and PR_ATTACH_NUM set to 0. There is no apparent difference
between the messages either.

Does someone know the magic logic behind the paper clip icon?

Thanks!

are the attachments all the same type of file?

Set a named property with GUID = {00062008-0000-0000-C000-000000000046} and
id = 0x8514
