HOWTO: Enable TLS 1.2 on a server running Zetadocs or the Zetafax Server



This technical note applies to:

  • Zetadocs
  • Zetafax Exchange Online Modern Authentication Update


Certain authentication functionality is failing with error messages or logs indicating that the server does not have TLS 1.2 installed or enabled, or you have been instructed to follow this from our Technical Support team. 


The resolution is to enable TLS 1.2 on the server in use which will ensure that all authentication from either Zetadocs or the Zetafax Exchange Online Update can be facilitated. Microsoft has a detailed guide on how to do this via Powershell and we recommend using this when enabling TLS 1.2.

Please follow this and ensure you restart the server, then re-test the functionality which was previously failing - this should now work as expected following these changes. 

If you are still having issues beyond this, please reach out to our support team for further assistance.
