We are developing an [Outlook Mail Addin](https://store.office.com/appshome.aspx?productgroup=Outlook) for our product. 

When i debug the solution in Visual Studio my Office365 Outlook account opens and i can see the plugin i developed in the list of outlook plugins and i can use it. 

The problem is that even after stopping the solution in Visual Studio i can still use the plugin. And when i re-run the solution it displays the cached version of the addin not the current version that i have in visual studio. 

Looks like the addin is cached somewhere. Can't seem to stop it.

How can i solve this problem?
