Outlook AddIn is deactivated because of long loading times
In some cases, the NoSpamProxy Outlook Add-in is deactivated due to long loading times. This article describes procedures for changing this.
- Long 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
This directory contains the DLL files for the Add-in, which change with every update. Thus the entire directory should be excluded from the real-time scan. - Prevent deactivation, despite long charging time
You can change the Load Behaviour for the Add-in, ideally to Load Behaviour = 3 in the registry.
