VS 2005 Outlook 2003 plugin was not running

When I am trying to test my Outlook 2003 plugin, I've noticed that there's no trace messages shown in Visual Studio's output window. Its very strange as it was working before and after a 3rd run it started to behave like that.

After some digging on the Internet I found out that Outlook had placed my plugin on its Disabled list. Solution is simply go to Outlook's About dialog screen then click on the Disabled Items button and re-enable my plugin.




The cause for this problem is that Outlook's Blacklist system would prevent a plugin from loading when there's a stop code or an exception had occured on the plugin's startup method. My only mistake here is that I did not read the entire message box stating that my plugin had experienced a serious error and if I want to disable it. I simply click YES and there began my headache. You probably know what's the moral lesson in here :D
