This documentation provided information about using TLS 1.1/1.2.
To maintain the highest level of security standards and comply with industry-wide best practices, we sometimes need to make security improvements. Recently, that meant disabling TLS 1.0 connections so we comply with higher encryption standards.
The Transport Layer Security (TLS) protocol ensures privacy between communicating applications and their users on the Internet. When a server and client communicate, TLS keeps third parties from eavesdropping or tampering with any message. TLS is the successor to the Secure Sockets Layer (SSL).
To disable TLS 1.0 and enable TLS 1.1 or 1.2
- In Internet Explorer, select Internet Options from the Tools menu.
- Click Advanced to see the following options:
- Use TLS 1.0
- Use TLS 1.1
- Use TLS 1.2
- Check 1.1 or 1.2. If both 1.1 and 1.2 are unchecked, the recipient will be unable to view the document. If your recipients can ensure that 1.0 is not the only option checked, they should be able to view the document as expected.
