HI bjrexpert, Thank you for your question. I understand that you are receiving an invalid security certificate when you log into eclipse webmail. It is also possible to manage your security certificates in the Advanced > Certificates menu. Click on View Certificates and open the one for the webmail. This should include an error why it is not valid. This is also reachable by right clicking on the webpage and selecting page info. You can remove the certificate and reload the page to prompt the server for a new one. What error are you receiving? *[[Add Security Exception]]
