Microsoft drops support for Internet Explorer 11 and legacy Edge

Microsoft drops support for Internet Explorer 11 and legacy Edge

Microsoft has announced that Microsoft 365 apps and services will no longer support Internet Explorer 11 (IE 11) by this time next year. Having already released the new Microsoft Edge and upgraded most of its Windows 10 customers to the new browser, Microsoft will be ending support for the Microsoft Edge Legacy desktop app on March 9, 2021.

Microsoft started working on Microsoft Edge nearly two years ago to enhance compatibility, security, easy and unified manageability, and productivity. The new Microsoft Edge will be built on the Chromium open source engine with Microsoft enterprise capabilities.

Microsoft has been moving existing Windows 10 users to the new Edge browser since its release in January this year. The company says that all new devices and future Windows feature updates will contain the new Microsoft Edge.

Beginning November 30, 2020, the Microsoft Teams web app will no longer support IE 11.

With the new Microsoft Edge and Internet Explorer mode, customers will not need an awkward workaround of one browser for some apps and another for other apps. However, using Internet Explorer mode in the new Microsoft Edge will not help to extend IE 11 access to Microsoft 365 apps and services beyond the support dates announced. After the end of the support date, the legacy version of Edge will not receive security updates.

Microsoft explained that while this change will be difficult for some customers, the company believes that customers will get the most out of Microsoft 365 when using the new Microsoft Edge. “We are committed to helping make this transition as smooth as possible. We believe that Microsoft 365 subscribers, in both consumer and commercial contexts, will be well served with this change through faster and more responsive web access to greater sets of features in everyday toolsets like Outlook, Teams, SharePoint, and more,” the statement added.

Beginning August 17, 2021, the remaining Microsoft 365 apps and services will no longer support 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.

“By the dates listed above, customers should no longer access Microsoft 365 apps and services using IE 11, but we want to be clear that IE 11 isn’t going away and that our customers’ own legacy IE 11 apps and investments will continue to work. Customers have made business-critical investments in IE 11 legacy apps and we respect that those apps are still functioning,” the statement concluded.
