I jsut wanted to let everyone I know I got it all working finally.
So here is what I did:
1) referenced the article: http://support.microsoft.com/?kbid=316653
2) make sure to go through the entire .il file, there are a lot of
places for _SinkHelper
3) At this point I tried to use the new file, but it was giving me a
signature exception related to the assembly not being signed properly.
I used SNRemove to remove the key from the assembly and now everything
is working.

thanks

I can use the this._outlookActiveExplorer).Activate += new

compiles fine, but when I start outlook 2000 or 2003 it says "No Such

I tried following the article:http://support.microsoft.com/?kbid=316653,
but when I started outlook after loading this my add-in did not load.
Any ideas?
