As previously announced by Microsoft in August 2020, along with other Microsoft 365 apps and services, Yammer will be retiring support for Internet Explorer 11 in August 2021. Customers should use the new Microsoft Edge, or another modern browser.
Timing: August 2021
Action: review and assess impact for your organization
How this affects your organization:
In August 2021, users will no longer be able to access Yammer and its integrations from Internet Explorer 11.
What you need to do to prepare:
We recommend that you deploy Edge or another modern browser, and begin communicating this change to IE11 users. Starting at the end of April, we will introduce a banner in the application directing IE11 users to use a new browser.
If you use Yammer embed, please note that this integration will also no longer be available on Internet Explorer 11 after August 2021. We recommend you start to move IE11 users off any sites you have that are using Yammer embed to Edge or another modern browser.
