title: VSTO Outlook: How to change email addresses in "To" field from compose window and avoid then to be applied to the rest of windows
body: <p>In the compose window and under some conditions I need to mark some email addresses in the &quot;To&quot; field with an asterisk at the beginning. The problem of doing so is that then I need to manage many use cases in which I need to remove the asterisk before (for example, before sending).</p>
  <p>Now I have seen that if you hold on the mouse over an email address in the &quot;To&quot; field, then a window is displayed offering you the possibility to add that email to your contacts. My problem is with this window in which the email address is displayed with the asterisk symbol at the beginning (see screenshot attached). So is there any way to remove the asterisk from that email address before it is shown in that window (but maintaining the asterisk in the &quot;To&quot; field in the compose window)?</p>
