I have tried a couple of times to set up a VPN but every time I have tried this my outlook 2016 emails get blocked is there a reason or a way round this. I have had problems before trying to send emails when abroad I wonder if this is related?
The only way I have found to send emails ending @ntlworld.com ( outloook various version) whilst I was away from home was to use a third party smtp server.
This seems to work but there I always worry that emails will get blocked because the spf/dmarc settings etc wont be correct and checking delivery logs is a pain
I installed a test VPN onto my router last night and down load speed fell from 76mb to 8mb !! and as I expected I couldn't get emails to send. (outlook 2013) I tried all the variations of authentication I could think of including changing from the ntlworld to virginmedia server names but they just would not send.
