We recommend using IMAP which is like cloud email where the messages stay on the server and synchronise to your computer, tablet, phone and webmail. You can also use POP if you simply want to download emails to your computer or you want a separate copy to each device.
Jezweb use two servers for our email hosting, Rackspace Mail and more recently Axigen Email. The configuration steps between both servers are essentially the same it is just the server information that is different.
If these settings do not work for you then contact us for assistance and we can talk you through the settings or provide a remote desktop link and configure your computer.
