MailItem.ReplyAll Event (Outlook)

Occurs when the user selects the ReplyAll action for an item, or when the ReplyAll method is called for the item, which is an instance of the parent object.

expression .ReplyAll(Response, Cancel)

expression A variable that represents a MailItem object.




Data Type





The new item being sent in response to the original message.




False when the event occurs. If the event procedure sets this argument to True, the reply all operation is not completed and the new item is not displayed.

Returns the reply as a MailItem object.

This Visual Basic for Applications (VBA) example uses the ReplyAll event and reminds the user that proceeding will reply to all original recipients of an item and, depending on the user's response, either allows the action to continue or stops it. To use this example, open an existing mail item, run the Initialize Handler() procedure, then reply to the item.

Public WithEvents myItem As MailItem 
Sub Initialize_Handler() 
 Set myItem = Application.ActiveInspector.CurrentItem 
End Sub 
Private Sub myItem_ReplyAll(ByVal Response As Object, Cancel As Boolean) 
 Dim mymsg As String 
 Dim myResult As Integer 
 mymsg = "Do you really want to reply to all original recipients?" 
 myResult = MsgBox(mymsg, vbYesNo, "Flame Protector") 
 If myResult = vbNo Then 
 Cancel = True 
 End If 
End Sub
