Configuring mobile from lap-top settings for email

Hi

I am a thicko when it comes to all this IT stuff so please treat me gently.

My question is I have recently reconfigured my lap-top's Windows Live Mail account settings using Windows 8.

It now works fine - both receiving and sending emails.

But I have a Galaxy S4 mobile which used to receive emails as well but since the recent change of settings, now does not.

I assume that the phone's server settings and so on must be IDENTICAL to that of the lap-top ?

I ask this daft question as I am receiving and seeing conflicting settings advice.

I have a BT [@btinternet.com] email address.

Also can anyone tell me what the CORRECT settings are - or is there no such thing ?

 Help !!!
