Distinguish between normal mail and attached mail

[Sonneck]

Hi all,

I try to find out, if a mail item is a "normal" mail item or if it is an attachment to another mail.

In the inspector-menu File -> Properties the property location is displayed. For a normal mail item this property displays the folder name where the item is saved. For an attachment the property has the value "Microsoft Office Outlook Embedded Message"

Does anybody know how to retrieve this information programmatically.

Perhaps you have other solutions how to make this distinction.

Thanks in advance

Georg
