Officemail users using Entourage on Mac OS are getting the following error message upon POP connection: "Unable to establish a secure connection to because the root certificate is not installed. If you continue, the information you view and send will be encrypted, but will not be secure".

  • Error occurs when opening Entourage and also when sending email.
  • Sending/Receiving works after accepting the prompt, but email is being sent unsecured.
  • Other email services (Xtra, Hotmail, etc) working fine in Entourage
  • Issue has been replicated on the test bench

The issue is affecting customers using Mac OS X 10.5.8 (or earlier) with the Microsoft Entourage email client.
