Email issue

I have a Mac and I use AOL email thru MS outlook. when I turn on the VPN protection, I am no longer able to send emails from AOL in outlook. I says that I am disconnected from the server. As soon as I turn the VPN off it works just fine. Any ideas?

Hello,
some ISPs don’t allow usage of their SMTP service, if the connection comes from outside of their network. I’m not completely sure if this is the case of AOL as well.

Best Regards,
