Send email to all contacts in Outlook address book when a new email received (VB) - vba

Question

I want to write a VBA script that when Outlook receive a new email from a specific email address , the VBA script has to detect that and resend the new received email to all contacts in the address book .
For now i was able to send an email to all contacts in address book :
Sub SendEmails()
Dim ContactsFolder As Folder
Set ContactsFolder = Session.GetDefaultFolder(olFolderContacts)
Dim Contact As Object
Dim olApp As Outlook.Application
Dim objMail As Outlook.MailItem
Set olApp = Outlook.Application
For Each Contact In ContactsFolder.Items
Set objMail = olApp.CreateItem(olMailItem)
With objMail
.Subject = "Subject of the received email"
.Body = "Body of the received email"
.To = Contact.Email1Address
.Send
End With
Next
End Sub
but how to use this script so it called when a new email received from a specific email address.
i tried to put this in ThisOulookSeassion to check for new message event so i could call my above code within it :
Private Sub Application_NewMail()
MsgBox "New mail"
End Sub
but it didn't work.
Also i tried this (i put it in ThisOulookSeassion too) :
Private WithEvents Items As Outlook.Items
Private Sub Application_Startup()
Dim olApp As Outlook.Application
Dim objNS As Outlook.NameSpace
Set olApp = Outlook.Application
Set objNS = olApp.GetNamespace("MAPI")
' default local Inbox
Set Items = objNS.GetDefaultFolder(olFolderInbox).Items
End Sub
Private Sub Items_ItemAdd(ByVal item As Object)
On Error Goto ErrorHandler
Dim Msg As Outlook.MailItem
If TypeName(item) = "MailItem" Then
Set Msg = item
' ******************
' and placing my code here.
' ******************
End If
ProgramExit:
Exit Sub
ErrorHandler:
MsgBox Err.Number & " - " & Err.Description
Resume ProgramExit
End Sub
but when i click run it ask me to create new macro and don't run the code.
Any suggestions ?

The simplest way is to create a rule in Outlook. Then you can assign an existing VBA macro to run when the rule is run. Typically a VBA sub should like the following one:
Sub SendEmails(mail as MailItem)
Dim ContactsFolder As Folder
Set ContactsFolder = Session.GetDefaultFolder(olFolderContacts)
Dim objMail as MailItem
Dim Contact As Object
For Each Contact In ContactsFolder.Items
Set objMail = olApp.CreateItem(olMailItem)
With objMail
.Subject = mail.Subject
.Body = "Body Text"
.To = Contact.Email1Address
.Send
End With
Next
End Sub
Also you may consider adding recipients to the Recipients collection and set their Type to the olBCC value. Thus, each of them will recieve a separate email and you have to submit only a single mail item.
