Hi

I am trying to develop a COM Add-In for outlook 2003 in VB6 (SP6). My
development machine is Windows 2003 server ( I normally develop web
apps).

I have followed the instructions and implemented IDTExtensibility2. I
have put no code other than a msgbox in the OnConnection event.

I can add the COM Add-In fine and it works - but only if I am running
the ActiveX project in the VB IDE at the time. If i shut outlook and
restart without the IDE running (have comiled and registered the DLL)
then Outlook does not laod the Add-In giving the message in the Add-In
dialog "Not Loaded. A runtime error occurred during the loading of the
COM Add-In."

The same DLL works OK on a Win2K server/Outlook 2000 machine, but not
on XP/Outlook 2000 which makes me think it is a XP/2003 issue. I tried
signing the DLL with a code signing cert issued by a trussted CA, but
this makes no difference.

Does anybody have any ideas?

Thanks in advance.

As you messed up the Outlook versions at the buttom of your message, is it
possible that the Add-In runs fine with Outlook 2003 and doesn´t with
Outlook 2000?

Hi Viele

Thanks for your reply.

I wrote the Add-In on a Windows 2003/Outlook 2003 environment. It will
only work on that platform running in the IDE.

The other environments I have tested it on a
1. Windows 2000/Outlook 2000 - works
2. Windows XP/Outlook 2000 - doesn't work
