I installed Zimbra Collaboration Suite 5.0 on CentOS, after installation, when i use Outlook, the certificate message appears saying "The server you are connected to using a security certificate that cannot be verified.
The target principal name is incorrect"
Issued to "my domain"
Issued by :my domain
Valid from 2009 to 2014
what does it mean please? and how can i resolve this to not appear again.
