The property is being set in an external application which created the email.
When I open the email in Oultook and look at the header information in the
message options, the headers with their values are shown. This is two of them
along with how its formatted:

X-PW-PROJECTID: 9
X-PW-SOURCE: Task Manager

Do you specify the property name in teh DASL format?
Are you sure that property exists? Can you see it in MFCMAPI or OutlookSpy?

Hello All,

Development Environment: Visual Studio 2008
Language: VB.Net
Outlook 2003 and 2008


Is it possible retrieve custom headers from an Outlook MailItem. I've been
trying to, but it seems that the "MailItem.PropertyAccessor.GetProperty"
method can only see Outlook's "core" headers.

Thanks,
