Thank you bjm. It worked a treat so can now leave VPN on all the time.

[Ronjos360]

Sorry all but I was mistaken. The VPN was switched off automatically and there for I thought I was testing with it switched on. The problem persists when it is switched back on.

and you’re adding thunderbird.exe?
what does Norton support say?

Try resetting Norton to default worked for me.

good morning, I’m trying to configure Thunderbird email, with the VPN turned on and split tunneling active on thunderbird.exe, it doesn’t work when sending or receiving emails… If I deactivate the Norton 360 VPN it works. How can I solve it? Thanks and best regards.
