Set the rules to copy to the target folders but not mark as read.
Put this untested code in the ThisOutlookSession module. Assumes the target folders are directly under the Inbox. If buried deeper, add .Folders as necessary.
Option Explicit
' one line for each target folder
Private WithEvents myOlItemsA As Outlook.Items
Private WithEvents myOlItemsB 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")
' one line for each target folder
Set myOlItemsA = objNS.GetDefaultFolder(olFolderInbox).Folders("targetfoldernameA").Items
Set myOlItemsB = objNS.GetDefaultFolder(olFolderInbox).Folders("targetfoldernameB").Items
End Sub
' one copy of ItemAdd code for each target folder
Private Sub myOlItemsA_ItemAdd(ByVal item As Object)
On Error GoTo ErrorHandler
Dim Msg As Outlook.MailItem
If TypeName(item) = "MailItem" Then
Set Msg = item
Msg.Unread = False
End If
ProgramExit:
Set Msg = Nothing
Exit Sub
ErrorHandler:
MsgBox Err.Number & " - " & Err.Description
Resume ProgramExit
End Sub
Private Sub myOlItemsB_ItemAdd(ByVal item As Object)
' same code as for myOlItemsA
End Sub
Code based on this post Using VBA to read new Outlook Email?
The rules move mail to target folders. The ItemAdd code acts on the items added to the target folders.
