Till Groupwise Client 7 we used (Clientside-)CDO 1.21 (5.5.2448.0) to create, fill and show (!) a new Mail.
With GW 8 (Evaluation) that doesn't work in the same way:
When I call (CDO.)Message.Send with 'ShowDialog = true' (to show the Mail befor really send) then the Windows Messenger opens and not the Groupwise Formular

I try to figure out what the problem is, and i found a difference in the registry key (IPM.Note):

HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{00020D3 1-0000-0000-C000-000000000046}\LocalServer32
Here GW 7 has overwritten the default value
C:\\Program Files\\Windows NT\\Windows Messaging\\exchng32.exe
C:\\Novell\\GroupWise\\grpwise.exe /mf /cm
(and additional creates a backup under LocalServer32SavedByGW).

GW 8 did not do that.
I manually change the key, but (of course) it didn't work: Groupwise completly opens, and not the mail-form. And the function 'send' hangs. After some minutes it comes a error: 'The form required to view this message cannot be displayed. Contact your administrator'. (Note: In GW 8 I can open Mails and all other Items correctly)

It seems so, that GW8 doesn't support a Formular for CDO-Mails anymore.
Have anybody experiences with this problemor have a hint? Is there a flag anywhere :-)?
Or I have to register some dll or exe manually?

Thank you for reading :-)
