As i'm using Firefox i decided to download Thunderbird. On the new account set up part i select Email account, then my name and HOTMAIL address. Next it asks me the type of incoming server i use - POP or IMAP. What are they?? It also asks the name of my incoming server. What's that?? I never used Outlook and to be honest i don't even know what this is used for!!! How thick am i!!!
