I have been tasked with figuring out how to kill our Add-In Express Outlook Plug-in on a fatal error without killing Outlook.

I tried ADXModule1.Finalize(). It does get rid of any forms that are displayed but not the Ribbon command bar. If my plug-in throws an exception and it is a fatal error, I want to completely unload the plug-in.

Hi Stephen,

Unfortunately, it is impossible to kill the plug-in without unloading the Outlook.
The only way is to find out where the error occurs and to fix it.
First try to get rid of the error by disabling all the events used by your add-in.
If that doesn't work, please send us your test project to replicate the issue.

It appears you can close and dispose of forms that you load. Is there a way to restart and reinitialize the plug-in programmatically? I mean if I determine I have a fatal error. I can disable(close, dispose, finalize) all of my Plug-In objects, how can I restart my plug-in (programmatically) without the user having to restart outlook?

Hi Stephen,

Depending on its logic every Addin can introduce some changes to the work of Outlook process.
When an unknown error occurs these changes need a rollback but it is impossible in this case without restating Outlook.
If you still want to disable the plug-in you can try to do this using OutlookApp.COMAddIns.Item(<IndexYourPlugIn>).Connect = false
