I have looked at the outgoing server and mine is 587 whereas my partners is 465. Could this be the problem! I don’t know how to change it though as I’ve tried adding server and doesn’t work.
It's probably not the cause of the problem but VM have been recommending everyone to use the 465 server for many years so you do need to update it. Exactly how you do that depends on which email app or client you are using to manage your emails. Which one are you using and on what device (mobile phone, laptop etc.)?
To troubleshoot your sending issue, try signing into your VM email account on the website. You can do that from here https://mail2.virginmedia.com/
Putting it simply, if you can send from the website then the problem is with your app and that raises a new set of questions.
If you cannot send from the website then the problem is with your VM email account itself and it can only be resolved by VM.
Post back here with how that test goes.
