Bitdefender Antispam won't stay turned on in Outlook 2016


Using Bitdefender 2018 Internet Security. In Outlook 2016, Bitdefender Antispam Com Add-in will not stay checked (turned on). I must manually turn this on every time I open Outlook 2016. Problem is occurring in 1 of 2 computers using the same Version of Windows 10 Home and Outlook 2016 (Office 365). So far no solution has been found.
