Outlook Add-in is deactivated due to long loading times

In some cases the NoSpamProxy Outlook Add-In is deactivated because of long loading times. This article describes procedures on how to change this.

Reduce loading times

If you have installed a local virus scanner on the client system, you should exclude the real-time scan for the following directory:

C:\Users\<<Username of the logged in account>>>AppData\Local\Assembly

In this directory are the DLL files for the Add-In, but they change with every update. The entire directory should therefore be excluded from the real-time scan

Prevent deactivation despite long charging time

You can change the Load Behavior for the Add-In - ideally to Load Behavior = 3 in the Registry.
