Hi sage12
Hope you are well!
You can find a guide to setting up the email here - that should give you all the settings you need to set up manually. If that does not work, we would have a chargeable IT Support desk who would be able to help, available on 0800 500 247, but in all honesty I think you would be better taking that to a phone shop to get checked out - if all the settings are in correctly and it still does not work, it could potentially be an issue with the phone itself, or the phones email client.
Hope you get this one sorted!
Regards
Ryan
