MAC - Outlook 16 / Office 365 - AVG blocking IMAP Sending

AVG has just started blocking IMAP email sending on Mac Outlook 16 / Office 365, I note it has been raised as an issue on Windows, but I cannot locate an option to disable as per the recommendation for windows, as follows?

Open AVG Internet Security, and navigate to > Menu > Settings > Basic Protection > Email Shield > Untick the "Scan outbound emails (SMTP)" checkbox.

Any assistance or recommendations for Mac users?
