We have installed zimbra 8.7 version on Ubuntu 14.04 and migrate emails from zimbra older version server(8.0.5) through ZeXtras. But we are getting issue in the new server getting all user’s password prompt on local MUA for authentication failure. Also found below error logs on server end. Can you check and provide us some solution for Zimbra8.7.
