title: How to retrieve Outlook.AddressEntry object from String with the mailbox address?
body: <p>I have as given String for example john@doe.com and I have to set up this as outgoing mailbox in a MailItem using the Sender setter in a C# VSTO project.</p>
  
  <p>This is my actual code (I let the full qualified name to indicate what I mean with MailItem):</p>
  
  <pre><code>Microsoft.Office.Interop.Outlook.MailItem mailItem = (Microsoft.Office.Interop.Outlook.MailItem) Globals.ThisAddIn.Application.CreateItem(Microsoft.Office.Interop.Outlook.OlItemType.olMailItem);
  mailItem.Subject = "Order #1";
  mailItem.To = "orderbot@doe.com";
  mailItem.Sender = (Here has to be the EntryAddress)
  mailItem.Display(false);
  </code></pre>
