Hi there. I've noticed that there are two possible servers for my live mail. Thunderbird Mail client sets up the server as:            imap-mail.outlook.com,  

whereas Windows Live Mail uses:            https://mail.services.live.com/DeltaSync_v2.0.0/sync.aspx.

Can anyone tell me what the difference is? Is one more reliable than the other? Can I switch servers in the email client? Thanks in advance.
