Hello Neville,

Once it is done, check the status with email and inform us here about the outcome.
Thank you.
Have now discovered that I cannot send emails (Outlook) through my VPN due to the VPN being listed by Spamhaus. This is the one in New Zealand. I am uncertain about other locations. However, as long as I close the VPN for sending emails, then there is no problem.
Neville, please follow the steps mentioned in this link and check for the issue again https://support.avg.com/SupportArticleView?l=en&urlName=Troubleshoot-AVG-Secure-VPN-email&supportType=home
Kindly follow the steps mentioned for Outlook.
Keep us posted.
