Norton 360 on Windows 10, fails email server connection

After installation of Norton 360 on my Windows 10 machine, my connect to my email server fails, even if I turn off the email antivirus filter. I am able to connect to the server using the same login on different machine. VPN  or firewall issue? The error that I get is a windows error that says that there was a failure to connect to the email server.

I have not tried it like that. How do I know if there are no more updates available?

 

Since your reinstall, have you run LiveUpdate manually a few times, restarting as necessary, until no updates are available? Then restart again. Restarting, not shutdown and startup again if you have Windows Fast Startup feature enabled.   If you use Windows 8/8.1 or 10, there can be an issue with the Windows Fast Startup feature.. See more information here.

I should say that my Gmail account continues to work, just the local account is not connecting.

it is a local ISP. I am using Outlook. 

My email uses SSL as well and I am not seeing any issue.

What email provider are you using? 

What email client are you using, or are you using web access to your email?

 

My email service uses SSL encryption. Autoprotect does not like that. I am going to try to change the service to POP3 or STMP and see if 360 is compatible with that. Hoping so...

Also, I did test it with VPN enabled before enabling the SONAR, and it worked with that on.

I uninstalled 360, then checked the connection ot the mail server. It worked fine. I then reinstalled 360 and turned off all of the security functions. Email worked still. I turned them on one at a time, testing the email connection after each one. I found that the 360 Computer AutoProtect/SONAR function is the culprit. Once enabled, it blocked the email server connection and would not allow it after even if disabled again. Apparently it changes a Windows setting that doesn't revert back. Another uninstall cleared it. Does any one know what specifically those Autoprotect and SONAR functions are doing?

 

If you have the VPN feature enabled, that could be causing your issue. Your email provider could be blocking access from known VPN IPs to protect your account from possible hacking. If you do have the VPN enabled, try disabling it and checking your email. If that works, you can add your email client to the VPN split tunnelling feature in 360. Open the My Norton interface in your 360 product. Then click on the down arrow beside the VPN feature and click on Settings. Then click on Split tunnel and then add the .exe for your email client.
