title: system.net.mail.attachments add error "Sorry something went wrong... "
body: <p>I'm using VB.NET and creating a new Mail outlook item using Microsoft.Interop.Outlook ver#15.</p>
  <p>I can create an Email object and set the Subject, Body, ToAddress, ccAddress, etc. just fine and display the new Email.</p>
  <p>I am having issues when I try and add a .pdf file via file path string to Attachments using the .Add method. Get an error &quot;Sorry something went wrong.. &quot; I have moved the file into different folders locally and same error.</p>
  <pre><code>Dim oApp As Outlook.Application = New Outlook.Application
  Dim mailItem As Outlook.MailItem = oApp.CreateItem(Outlook.OlItemType.olMailItem)
  
  mailItem.Subject = _sSubject
  mailItem.To = sToAddress
  mailItem.CC = sCCAddress
  mailItem.Body = sBody
  
  ''Commented out for now Until I can figure out error!! 
  For Each _File As String In sAttachList
      Dim _AttachObject As New System.Net.Mail.Attachment(_File)
  
      mailItem.Attachments.Add(_AttachObject)
  
  Next
  
  mailItem.Importance = Outlook.OlImportance.olImportanceNormal
  mailItem.Display(True)
  mailItem = Nothing
  oApp = Nothing
