Add-In program does not work in Outlook 2000 SR-1

My Add-In program developed in .NET 2003 works well in Outlook 2003.
But it does not work in Outlook 2000 SR-1. When I launched Outlook 2000 SR-1,
I got an error -- "Object reference not set to an instance of an object"
My Add-In program uses a reference of Outlook XP PIA
( microsoft.office.interop.outlook.dll) and some references of
Framework V1.1.4322.

I'm wondering what is wrong, how to solve this problem.

Thanks a lot
Mike
 
Thank you, ken for your replying.
I checked the link you gave. I found that Microsoft does not offer a PIA
for Office 2000. So my problem is to how to build a PIA for Office 2000.

I appreciate your help very much.

The bottom of that page I linked you to has information about that.
 
Thank you, Ken.
I tried to rebuild the Outlook Interop Assembly based on the article.
However, when I searched "_SinkHelper" in Interop.Outlook.il, I found that
_SinkHelper classes were already Public. I could not do any change.
The version of Interop.Outlook.dll I used is 9.0.0.0.
I'm wondering if there is something wrong.

Thanks
Mike
 
I'd start a new thread about this so someone else can answer. I don't find
managed code addins for Outlook a compelling story so I'm not really
familiar with the ins and outs of modifying PIA's. You might also try
googling for this, I'm sure there's information out there somewhere.
