Salesforce TLS 1.2 changes and Chatter for SharePoint

Hi Everyone. Wanted to make my customers aware of a security change that Salesforce is beginning to phase-in which will impact the Chatter for SharePoint product. Effective October 25, 2019, Salesforce will remove support for TLS 1.1 protocol encryption (Sandboxes will be updated on September 20, 2019). Chatter for SharePoint versions below 3.1 use TLS 1.1 to communicate with the Salesforce Chatter API. An update will be required to continue using the products after the TLS changes are implemented.

Affected Products:

  • Chatter For SharePoint 2010 (All versions)
  • Chatter for SharePoint 2013/2016/2019 (prior to 3.1)
  • Chatter for SharePoint Online (prior to version 3.1)

Due to limitations in the Microsoft .NET Framework supported by SharePoint 2010 it is not possible to implement TLS 1.2 protocol encryption in this version. The 2010 version of Chatter for SharePoint will stop functioning once Salesforce implements this change. Customers still on SharePoint 2010 are strongly encouraged to migrate to a newer supported version of SharePoint.

Updates for the supported SharePoint On-Premises and Online versions will be available within the next week or so. SharePoint Online customers will receive the update automatically as part of their subscription. OnPrem customers will need to download and deploy the new version before Salesforce implements their change.
