Problem with UserPorperties in eMails

[Guest]

Hello,

My Add-In adds a new Property to eMails. I use the typelibraries for
Outlook2000.
The Add in is developed in Delphi.

The userdefined field 'Printed' will set in the Inspector but not in the
INBOX-Folder.

In Inspector:

var AMailItem: MailItem;
AUserProperty: UserProperty;

AMailItem := FOutlookApp.ActiveInspector.CurrentItem as MailItem;
AProp := AMailItem.UserProperties.Find('Printed', EmptyParam);
if AProp = Nil then begin
AProp := AMailItem.UserProperties.Add('Printed', olText, True, EmptyParam);
AProp.Value := 'YES';
end
else begin
AProp.Value := 'YES';
end;
AMailItem.Save;

In the Inspector it works correct

In Folder (InBox):

AMailItem := FOutlookApp.ActiveExplorer.Selection.Item(1) as MailItem;
AProp := AMailItem.UserProperties.Find('Printed', EmptyParam);
if AProp = Nil then begin
AProp := AMailItem.UserProperties.Add('Printed', olText, True, EmptyParam);
AProp.Value := 'YES';
end
else begin
AProp.Value := 'YES';
end;
AMailItem.Save;

In the INBOX-Folder it not works. No Error - but the Field will not displayed.

Can someone help me?

Did you actually step through your code? If UserProperties.Find cannot find
a property, it raises an error (DISP_E_UNKNOWNNAME), but you never trap it.

Hi Dmitry

I tested it. That is not the problem.

When i cannot find the property, i add it to the 'AmailItem'.
After adding the property i can find it, but the property will not saved and
i cannot see it in the Folder.

I hope this helps you. Franz

I had no problem running the following VB script. Does it work for you?

set Msg = Application.ActiveExplorer.Selection.Item(1)
on error resume next
err.Clear
set prop = msg.Userproperties.Find("Printed")
if (prop is Nothing) or (err.Number <> 0) Then
set prop = msg.UserProperties.Add("Printed", olText, true)
End If
prop.Value = "YES"
msg.Save
