The whole point of retrieving the value of the Class property is to make
sure trhat you really have a MailItem object.
Try the following script in OutlookSpy: click Application button on the
OutlookSpy toolbar, go to the Script tab, paste teh script below. Now
whenever a new message arrives, OutlookSpy will open a new IDispatch browser
where you shoudl be able to see all the object properties.

sub Application_NewMailEx(EntryIDCollection)
set Msg = Application.Session.GetItemfromID(EntryIDCollectio n)
BrowseObject(Msg)
end sub

No, i don't think so, i'm sure it is a MailItem, because it is my test
e-mail
(It is the case, my outlook have two accounts, A and B, i Use A send an
encrypted e-mail to B, and receive this e-mail, then the plugin will enter
OnNewMailEx(BSTR entryId) function.).

I got it, i can use GetIDsOfNames to get a class property of this income
item,
but i can't get MailItem, am i right?

That means the message is not a MailItem. Could be ReportItem,
MeetingItem,
etc.
The first parameter in GetIDsOfNames is the name of the property, e.g.
"Class".

The result of run script is: The MailItem property page is shown. I have
no

the
_MailItemPtr even it is encrypted Mail item??
