The easiest way to disable SonicWALL is through the system tray by right-clicking the program's icon and selecting "Disabling SonicWALL." If Outlook or Outlook Express is open, the change takes place once those systems are closed; otherwise, it happens immediately.
Disabling this feature means that it does not start when Outlook or Outlook Express is opened. It also stops filtering spam or phishing emails. The program can be easily re-enabled at a later time by right-clicking the program's icon and then selecting "Enable SonicWALL." As with disabling the application, Outlook needs to be restarted before the changes take effect.
