body: <p>I am using MailKit and calling this, which works most of the time. </p>
  
  <pre><code>imap.Inbox.Open(FolderAccess.ReadOnly);
  </code></pre>
  
  <p>From time to time some servers and accounts, including my own gmail account, refuse to let me read them:</p>
  
  <pre><code>The IMAP server replied to the 'EXAMINE' command with a 'NO' response.
  </code></pre>
  
  <p>Is this something I could prevent? Too many calls or conflicting with another mail client reading at the same time? It is quite hard to test these theories and maybe somebody knows?</p>
