Continued Support for the Outlook Integration in Older Versions of Outlook and Windows

We are continuing support for the Outlook integration in Outlook 2013, Outlook 2016, and volume-licensed versions of Outlook 2019 through the end of December 2021. Previously, we announced that Outlook integration users running these versions would lose access to the integration when support for Internet Explorer 11 in Lightning Experience ended in December 2020. This continued support applies only to the Outlook integration. It doesn’t apply to Salesforce for Outlook or using Internet Explorer 11 to access Lightning Experience.

Where: This change applies to the Outlook integration, formerly known as Lightning for Outlook, in all editions.

Who: This change applies to all users running the Outlook integration in older versions of Outlook, including Outlook 2013, Outlook 2016, or volume-licensed Outlook 2019.

Why: We heard you. Now isn’t the best time to upgrade your systems to continue using the valuable features in the integration. To continue using the Outlook integration after the end of 2021, make plans now to upgrade. After December 2021 you need Office version 16.0.11629 and later, and Windows 10 versions 1903 and later.

To ensure that you have the latest Microsoft security and product updates, we always recommend running the latest versions of Outlook and Windows. Plus, the Outlook integration is built on the Microsoft Add-in Framework. Original versions of that framework use Internet Explorer 11 to launch the Salesforce add-in from desktop versions of Outlook. That requirement was true for all add-ins built on that framework, not just the Salesforce add-in. The latest versions of the Add-in Framework use Microsoft Edge to launch the add-in. Edge is the native browser available in newer versions of Windows. We continue to build the Outlook integration on the latest framework version to use the latest technology.

How: The Outlook integration runs as it has in previous releases, even on older versions of Outlook and Windows. But Lightning Experience support for Internet Explorer ends on December 31, 2020. Errors can then result if reps use older versions to launch Salesforce from the integration.
