As an admin of a Salesforce org, we would like to inform you that Salesforce will disable TLS 1.0 in a phased schedule which started on July 22, 2017. Every admin of an org that still uses TLS 1.0 has already received notifications from Salesforce about the disablement.
This article is an extra reminder in addition to these notifications. This only applies if you still use TLS 1.0.
If you do not know what TLS 1.0 is or are unsure of what actions you need to take to prepare for the disablement of this encryption protocol, Salesforce has provided the Salesforce disabling TLS 1.0 article for review. If you use Internet Explorer, Salesforce has provided the article Enabling TLS 1.1 and TLS 1.2 in Internet Explorer.
To ensure the TLS 1.0 disablement process goes as smoothly as possible, Salesforce will use a phased schedule that begins on July 22 (on Sandboxes) and runs through November 11, 2017. To find out when your Salesforce instance will be disabled, please review the TLS 1.0 Disablement Schedule article. It’s important to note that since Salesforce is disabling TLS on an instance-by-instance basis, it will NOT be possible to change the date of your disablement.
What should I do now?
Please take the needed steps as outlined in the Salesforce disabling TLS 1.0 article and upgrade to TLS 1.1 or higher by July 22.
