Prepare your SharePoint and OneDrive environment for end of support for Internet Explorer 11

Reference ID: MC257029 | Effective: August 17, 2021

MC257029 – As shared in MC220490 last year, Microsoft 365 apps and services will not support Internet Explorer 11 (IE 11) after August 17, 2021. 

How this will affect your organization:

Once this change takes effect, Microsoft 365 apps and services, including SharePoint Online and OneDrive, will not be supported on IE 11. This means that after the above dates, customers will have a degraded experience or will be unable to connect to Microsoft 365 apps and services on IE 11. For degraded experiences, new Microsoft 365 features will not be available or certain features may cease to work when accessing the app or service via IE 11. While Microsoft knows this change will be difficult for some customers, they believe that they will get the most out of Microsoft 365 apps when using the Microsoft Edge browser. Microsoft 365 users will be well served with this change through faster and more responsive web access to greater sets of features in everyday toolsets. 

What you need to do to prepare:

As this date comes closer, Microsoft is committed to helping make this transition as smooth as possible for customers and have identified considerations and practices for admins to help transition off classic SharePoint features that rely on Internet Explorer 11. If you use IE11 browsers to access SharePoint or OneDrive content, Microsoft strongly recommends you to review the guidelines posted in this article and take the necessary action before August 17, 2021 so there is no service disruption for users: Prepare your SharePoint and OneDrive for Business environment for the retirement of Internet Explorer 11.

Admins can monitor the IE11 browser usage for their tenants in Admin Center. Check this article to review your browser usage: Microsoft 365 Reports in the admin center – Microsoft browser usage – Microsoft 365 admin | Microsoft Docs

If your organization already finished upgrading to Microsoft Edge, no further action would be needed.Additional informationHelp and support
