Mail sending through macro

Hi All,

I have a VB code to send a mail from excel. And I want few changes has to be done in the macro.
1. I want to change code to send mails from windows live, as I am not using outlook.
2. I need the mail to send according to time which I can set.

Please find the below mentioned code.

Sub Test1()
'For Tips see: http://www.rondebruin.nl/win/winmail/Outlook/tips.htm
'Working in Office 2000-2013
Dim OutApp As Object
Dim OutMail As Object
Dim cell As Range

Application.ScreenUpdating = False
Set OutApp = CreateObject("Outlook.Application")

On Error GoTo cleanup
For Each cell In Columns("B").Cells.SpecialCells(xlCellTypeConstants)
If cell.Value Like "?*@?*.?*" And _
LCase(Cells(cell.Row, "C").Value) = "yes" Then

Set OutMail = OutApp.CreateItem(0)
On Error Resume Next
With OutMail
.To = cell.Value
.Subject = "Reminder"
.Body = "Dear " & Cells(cell.Row, "A").Value _
& vbNewLine & vbNewLine & _
"Please contact us to discuss bringing " & _
"your account up to date"
'You can add files also like this
'.Attachments.Add ("C:\test.txt")
.Send 'Or use Display
End With
On Error GoTo 0
Set OutMail = Nothing
End If
Next cell

cleanup:
Set OutApp = Nothing
Application.ScreenUpdating = True
End Sub

Any idea about it?
