SSL/TLS Incompability Issues

Last updated: January 16, 2019

With our newer servers enforcing the more recent SSL/TLS protocols as a standard and disallowing older SSL2/SSL3 ciphers there have been some customers who have run into SSL/TLS protocol errors when using email on third party software on older operating systems.

This is for security advancement purposes, as we cannot continue to allow insecure and depreciated versions of SSL/TLS operate on our servers given that they are infrequently updated, and have massive security flaws and can be detrimental to the integrity to our servers.

How do I know if this will affect me?

Most people nowadays use computers with Windows 10, however, older operating systems such as Windows 7 and versions of mail software like Outlook 2013 will have an extremely tough time connecting to new TLS versions.

It is unfortunate if you’re running into this issue, however, there are a few things you can do to resolve this:

  • Source a more recent email software application for checking email accounts, that can connect over new SSL/TLS protocols.
  • Upgrade your operating system and Outlook installation to more recent versions, such as Windows 10 and newer versions of Outlook.
  • Organise or contact an IT technician to attend or connect to your system and apply a registry update to enable SSL/TLS support.

It is strongly recommended to simply update your operating system and mail software, given that this is a future-proof solution.

You can work with your current set up provided an IT technician can sort you with a work around, however, these protocols are soon to be depreciated – even by Microsoft, so whilst it may be convenient for a temporary work around, you will eventually have to get with the times.
