Currently I am checking how to modify Outlook 2007 default view by using vbs.

Following is my working vbs. You can download and test it.

VBS code example

Const ForReading = 1
Const olFolderInbox = 6
Const olColorRed = 10
Set olApp = CreateObject("Outlook.Application")
Set objName = olApp.GetNameSpace("MAPI")

Set objTableView = objName.GetDefaultFolder(olFolderInbox).CurrentView

            objTableView.ColumnFont.Size = 10
            objTableView.ColumnFont.Name = "Arial"

            objTableView.RowFont.Size = 10
            objTableView.RowFont.Name = "Arial"

            objTableView.AutoPreviewFont.Name = "Arial"
            objTableView.AutoPreviewFont.Size = 10

            ' Save the table view.
            objTableView.Save
            objTableView.Apply

        Set objView = objName.GetDefaultFolder(olFolderInbox).CurrentView

        For Each objRule In objView.AutoFormatRules

           If Not objRule.Name = "Unread group headers" Then

                'MsgBox objRule.Name
		'MsgBox objRule.Font.Color

                objRule.Font.Color = olColorRed

           End If
           objRule.Font.Size = 10
           objRule.Font.Name = "Arial"

        Next

        objView.Save
        objView.Apply

wscript.echo "Completed"
