Thank you for the answer Amos! I will see the possibility of updating the version. I also have to evaluate the possibility that this error is due to some of my users using mail services on their smartphones and are authenticated against my AD Servers . I'm not sure if it can be or not... I have to analyze it. Thanks again.
