your server does not support the connection encryption type you have specified

Version 1.0 of the TLS protocol is not secure. As such it needs to be disabled on servers which want to have a PCI compliance. Our servers are PCI compliant by default, which is why we have disabled TLS 1.0 on them.

On Windows 7 and Windows 8.0 computers, the applications built on WinHTTP (Windows HTTP Services) such as Outlook, Word, etc. only support TLS 1.0. As a result of this, if you try to establish a secure connection from your Outlook client to  server, Outlook will throw an error message "your server does not support the connection encryption type you have specified".

In order to resolve this and allow your Outlook to communicate securely to the server using TLS 1.1 and TLS 1.2, you have to do the following:

  2. Download the file MicrosoftEasyFix51044.msi from the following page and install it on your computer:
