Reminder: Your Microsoft 365 applications will soon be incompatible with Internet Explorer 11.

On July 23rd, Microsoft issued a reminder stating that starting August 17th, 2021, Microsoft 365 applications and services will no longer be supporting Internet Explorer 11 (IE11).

Beginning August 17, 2021, Microsoft 365 apps and services will no longer support Internet Explorer 11 (IE11) and users may have a degraded experience, or be unable to connect to, those apps and services. These apps and services will phase out over weeks and months to ensure a smooth end of support, with each app and service phasing out on independent schedules,” warned Microsoft.

Further, Microsoft warned that support and user experience will begin steadily decreasing on August 17th, stating, “If you encounter issues while accessing Microsoft 365 apps and services from IE11 after August 17, 2021, support will be unavailable. Additionally, you should expect no new features and that your daily usage experience could get progressively worse over time until the apps and services are disconnected.

The following is a summary of the application experience that users will encounter with Internet Explorer 11, effective August 17, 2021:

Outlook Web App: Users logging in with AAD accounts will still receive the full OWA experience but will not receive new features beginning August 17, 2021, while users logging in with Microsoft Accounts (MSA) will be redirected to the Outlook Web App Light experience.

Open with Explorer/View in File Explorer (SharePoint): We understand that some customers may continue to use Open with Explorer and View in File Explorer (only accessible in IE11) to access document libraries. To avoid disruption, these customers will be able to use these features for now when they go to a document library in IE11. These features remain in maintenance mode and aren’t receiving further development. We encourage all customers to move to a modern browser and OneDrive sync for a better user experience and easier access to files. For more information on how to prepare your SharePoint environment for end of support on IE11, please read this Docs article.

All other apps and services will phase out over weeks and months to ensure a smooth end of support with each app and service phasing out on independent schedules.
