Run a script rule: Autoreply using a template

This macro will reply to the person who sent the message. It includes the original message, any text entered by in the macro, plus the content of the template.

Because this is a run a script rule, all messages meeting the condition will be replied to, unlike the autoreply rule which is one message per Outlook session.

If you want to include the original subject, use (or add) item.subject to the .Subject field, otherwise, this should have most of the bases covered and point you in the right direction for things I didn't include. Remove the parts you don't need and you should be good to go....

Keep in mind that the original message is Item, from Item As Outlook.MailItem. oRespond is the message you are sending back. You need to use the Item fields if you want to include fields from the original message in the response.

Sub AutoReplywithTemplate(Item As Outlook.MailItem)
Dim oRespond As Outlook.MailItem

' Use this for a real reply
' Set oRespond = Item.Reply

' This sends a response back using a template
Set oRespond = Application.CreateItemFromTemplate("C:\path\to\template.oft")

With oRespond 
    .Recipients.Add Item.SenderEmailAddress
    .Subject = "Your Subject Goes Here"
    .HTMLBody = "Your reply text goes here." & vbCrLf & _
              "---- original body below ---" & vbCrLf & _ 
               Item.HTMLBody & vbCrLf & _ 
             "---- Template body below ---" & _ 
               vbCrLf & oRespond.HTMLBody

' includes the original message as an attachment
    .Attachments.Add Item

' use this for testing, change to .send once you have it working as desired
    .Display 
End With
Set oRespond = Nothing
End Sub

Autoreply to Reply To Address, Not Sender

If you use a web form that comes from a generic address with a Reply to address set, you can use a simple macro to Reply to the message. Unlike the autoreply rule which replies to the sender, this reply is the same as hitting the Reply button yourself.

Sub ReplytoReplyTo(Item As Outlook.MailItem)
Dim oRespond As Outlook.MailItem

Set oRespond = Item.Reply

' use for testing
 oRespond.Display
 ' oRespond.Send
 
 End Sub

Reply to a web form generated message

If you want to reply to a person who fills out a web form but the email that is generated is from a generic email address and their address is not in the Reply to field, you can use RegEx to get the address from the message body.

Sub SendNew(Item As Outlook.MailItem)
   Dim Reg1 As Object
    Dim M1 As Object
    Dim M As Object
    Dim strAddress As String

Set Reg1 = CreateObject("VBScript.RegExp")

    With Reg1
       .Pattern = "(([\w-\.]*\@[\w-\.]*)\s*)"
       .IgnoreCase = True
       .Global = False
    End With

If Reg1.Test(Item.Body) Then
     
        Set M1 = Reg1.Execute(Item.Body)
        For Each M In M1
           strAddress = M.SubMatches(1)
        Next
    End If

 Dim objMsg As MailItem
 Set objMsg = Application.CreateItemFromTemplate("C:\path\to\template.oft")

 objMsg.Recipients.Add strAddress

 ' Copy the original message subject
 objMsg.Subject = "Thanks: " & Item.Subject

' use for testing 
 objMsg.display 

 ' objMsg.Send

 End Sub

Reply with a template

When you want to reply with a template, you need to "pick up" information from the selected message. This macro works with an open or selected item and needs the GetCurrentItem function found here. If you will only ever use it with selected items (or open items) you can change the code to use current item or selection. More information is available at Outlook VBA: work with open item or selected item.

Sub ReplywithTemplate()
Dim Item As Outlook.MailItem
Dim oRespond As Outlook.MailItem

' need function fromhttp://slipstick.me/e8mio
Set Item = GetCurrentItem()

' This sends a response back using a template
Set oRespond = Application.CreateItemFromTemplate("C:\Test\template.oft")

With oRespond
    .Recipients.Add Item.SenderEmailAddress
    .subject = "Your Subject Goes Here"
    .HTMLBody = oRespond.HTMLBody & vbCrLf & _
              "---- original message below ---" & vbCrLf & _
               Item.HTMLBody & vbCrLf
               
' includes the original message as an attachment
    .Attachments.Add Item

' use this for testing, change to .send once you have it working as desired
    .Display
End With
Set oRespond = Nothing
End Sub
