Today, we’re announcing that Microsoft 365 apps and services will no longer support Internet Explorer 11 (IE 11) by this time next year.

 

  • Beginning November 30, 2020, the Microsoft Teams web app will no longer support IE 11.
  • 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. While we know this change will be difficult for some customers, we believe 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.

 

Customers have been using IE 11 since 2013 when the online environment was much less sophisticated than the landscape today. Since then, open web standards and newer browsers—like the new Microsoft Edge—have enabled better, more innovative online experiences. 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.

 

Respecting investments in IE 11 web apps

 

We understand the need to “do more with less” in the new business environment. 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 away1 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.

 

In this moment of bridging between modern and legacy apps, many customers may feel there is no choice but to rely on a two-browser workaround of using IE 11 alongside a modern browser. However, with the new Microsoft Edge and Internet Explorer mode, customers don’t need an awkward workaround of one browser for some apps and another for other apps. They can standardize on one browser and seamlessly experience the best of the modern web in one tab while accessing a business-critical legacy IE 11 app in another tab – all housed within the new Microsoft Edge.

 

With native integration in Microsoft management, security, and productivity tools, we recommend the new Microsoft Edge to address our customers’ compatibility and secure remote work needs. Microsoft Edge has SmartScreen built-in and has the highest-rated phishing and malware protection as measured by two independent studies. We will also support our customers’ transition to the new Microsoft Edge with app and site compatibility assistance. As part of the App Assure promise, we have Microsoft engineers ready to help customers in case they run into compatibility issues. For more information, see the ‘Help is available’ section below.

 

Note: 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 dates listed above. Microsoft 365 apps and services will stop supporting IE 11 on the dates listed.

 

Microsoft Edge Legacy makes way for the new Microsoft Edge

 

Nearly two years ago, we started working on the new Microsoft Edge, listening to our customers’ needs for world-class compatibility (including legacy app support), security, privacy, easy and unified manageability, and productivity. The result is a whole new Microsoft Edge from the inside out: a browser built on the Chromium open source engine with the latest in Microsoft enterprise capabilities. Since its release in January, millions of users have upgraded their home and work browsers to the new Microsoft Edge. Additionally, new devices and future Windows feature updates (starting with Windows 10, version 20H2) will contain the new Microsoft Edge.

 

Now that we’ve shipped the new Microsoft Edge, and upgraded most of our Windows 10 customers to the new browser, we’re ending support for the Microsoft Edge Legacy desktop app on March 9, 2021.

 

  • After March 9, 2021, the Microsoft Edge Legacy desktop app will not receive new security updates.

The new Microsoft Edge is our best expression of a modern browser—we’re excited for customers to experience it. Apps and sites created for Microsoft Edge Legacy will continue to work in the new Microsoft Edge, but if a compatibility issue does arise, we have our App Assure promise to provide support. For more information, see the section below.

 

Help is available

 

For customers using IE 11 to access Microsoft 365 apps and services, or using Microsoft Edge Legacy as their preferred browser, we recommend the new Microsoft Edge and offer a range of support options to help transition.

 

To begin, we recommend that customers first read this detailed article about how to plan for deployment. The article guides customers through key questions and offers a path forward for major steps in the transition to the new Microsoft Edge.

 

Next, customers should determine what type of support they are looking for, if any.

 

Customers with Microsoft Unified Support can reach out to that support service for help transitioning to the new Microsoft Edge.

 

For customers who would like guidance on how to plan, deploy, or adopt the new Microsoft Edge, there’s FastTrack. FastTrack is available at no additional charge to customers with 150 or more paid seats of Windows 10 Enterprise. To get started, submit a Request for Assistance through the FastTrack site.

 

And for those customers who prefer to get started on their own, we have self-guided deployment and configuration materials, complete with a series from Microsoft Mechanics, ready on our Docs site.

 

Finally, it is natural for customers to be concerned about compatibility when it comes to business-critical apps and sites. This is why we offer compatibility “peace of mind” with App Assure. The App Assure promise is this: if customers’ web apps and sites work on IE 11, supported versions of Google Chrome, or any version of Microsoft Edge (including Microsoft Edge Legacy), those web apps and sites should work on the new Microsoft Edge. If not, they can contact App Assure for remediation support here or by email (ACHELP@microsoft.com). Assistance is provided in Traditional Chinese and Simplified Chinese (support specialists speak Mandarin only), English, French, German, Italian, Japanese, Korean, Portuguese (Brazil), and Spanish.

 

Higher performance, simpler security on a single browser standard

 

At a time when IT professionals are being asked to do more with less on an unprecedented level, we want to make it simple for our customers to balance productivity, security, privacy, and cost.

 

To learn more about the new Microsoft Edge, customers can check out our website and the How to Get Started End User Guide.

 

We’re grateful for the trust you have placed in Microsoft through the years. We’re here to help and can’t wait for you to experience Microsoft 365 on the new Microsoft Edge.

Ummm. We still have a SCOM 2012 R2 server and last I checked by our SCOM team, it is only accessible by IE11 and Silverlight. Any options?

 

When will IE11 be finally killed off - as in no updates?

New Contributor

At some point in development will Edge natively support SharePoint "View in File Explorer"? Will Microsoft completely rewrite File Explorer access to SharePoint Online to work natively in Edge, removing the dependency on the ActiveX control.

Internet Explorer 11 is a component of the Windows operating system and follows the Lifecycle Policy for the product on which it is installed.

Legacy Edge is also a component of the Windows operating system and should also follow the lifestyle for the product on which it is also installed, not cut short over a year before Enterprise support for 1909 ends.

@Edward_BYou should be able to use Chromium Edge's IE11 compatibility mode to connect to the SCOM 2012 R2 / 2016 web console. The IE11 components themselves will continue to receive security updates for many years to come (at least as long as the lifetime of Server 2019 and Windows 10 LTSC 2019) as there are a lot of third-party applications that (sometimes unknowingly) have taken dependencies on bits and pieces of that stack of technology.


Hope you can get budget for a SCOM 2019 upgrade... it was a good version for its time but you really shouldn't be using 2013 tech to manage systems in the 2020s.

@Gary Schultz 
Thank you for reaching out about "View in File Explorer"! 

 

For customers who have taken a dependency on File Explorer, its use will continue to be supported until August 17, 2021.  We recommend that rather than use the Open with Explorer command, a better option is to sync your SharePoint files or move or copy files in SharePoint.  

 

Since SharePoint Open with Explorer uses ActiveX technology, it's only supported in Internet Explorer. Open with Explorer doesn't work in Windows with Microsoft Edge, Google Chrome, or Mozilla FireFox, or on the Mac platform. 

 

The ActiveX control is only needed when you're working with files in Windows File Explorer. Once you're done with File Explorer, you can then use any supported browser with SharePoint.

Don't you think we would be using those options if they worked better than File Explorer view. The truth is that moving and copying files inside SharePoint sucks big time. There is no bigger headache for our users (and thus me) than having to deal with the myriad problems with moving files inside of SharePoint and OneDrive. How many times does this feedback have to be given to Microsoft? Don't take away old features until you can match or surpass them.

A question that was not very clear in the ad: does the end of Edge Legacy support mean the end of EdgeHTML support? Is EdgeHTML officially considered a Windows component? What will happen to EdgeHTML after the date stipulated as the end of Edge Legacy on still supported versions and editions of Windows 10 after March 9, 2021, such as LTSB 2015, LTSB 2016, LTSC 2019, Windows Server 2016 and 2019, 1909 , 2004 and 20h2?

Hello @M365_Edge_ProductTeams 

 

Good news!

I recently received a pptx from Microsoft with Youtube videos embedded and there is an error as I don't have IE 11 activated....So when are you getting rid of this dependency

 

Thanks

Senior Member

Well, it's a very short period for Teams.

If you're linking to Teams from a SharePoint site on IE11, you'll need to switch to Edge only teams. I don't have enough time!

Microsoft 365 に Forms は含まれますか?

不特定ユーザーからアンケートを行う時に Internet Explorer 11 でアクセスしないでほしいというのは難しい。

OneDrive for Business の共有や Azure Information Protection の復号も同じです。

パブリックアクセスのある機能はブラウザ制限が入るべきではない。

Occasional Visitor

"Does Microsoft 365 include Forms?"

 

This is a good point. If we were to create a Quiz in Edge/Chrome, and send it to others to fill in, will the recipients of the survey be able to open the quiz using IE11 in order to respond to it?

Good move, ditch the IE11 once and for all :smile:

When will Developer Tools properly support IEMode? Now we need to revert to IE11 still for this functionality.

New Edge is not available on Windows Server yet. And it should come into all Windows Servers that are supported: 2012, 2012 R2, 2016 and 2019.

When will there finally be a reasonable engine for older Outlook versions?

The Beta of Edge Chromium had 2012 r2/2016 and 2019 support when are the server versions going to be officially released?  Not being able to use the same browser on the server to check web pages, use Windows Admin center, etc as the Windows 10 clients is sub-optimal.

Hi @Warner777 and @Mantvydas ,

 

The Windows platform downloads apply to all supported client and server releases of Windows - check out the entire list of supported platforms here: https://docs.microsoft.com/en-us/deployedge/microsoft-edge-supported-operating-systems

Hi @Bruno_A_Vieira,

 

While support for Microsoft Edge Legacy will end after March 9, 2021, EdgeHTML will remain supported.

Will you publish a full list of M365 products and services that have IE11 only features and what those features are, such as SharePoint Online's Open with File Explorer? If so it would be good to also document the replacement technology/feature for each one. Thanks!

Occasional Visitor

Will this affect the WebBrowser OLE object? We use that to display and edit (with Design Mode) HTML in an application used by thousands of users.

New Contributor

@M365_Edge_ProductTeams

 

As has been stated "Don't you think we would be using those options if they worked better than File Explorer view. The truth is that moving and copying files inside SharePoint sucks big time."

 

Copying/Moving files in SharePoint in the browser has issues. Whenever I try copy/move in the browser, I cannot access every SharePoint Online site I am a member of. Therefore, the copy/move feature is not effective. 

We are working on a project in which files containing confidential information are not suppose to touch the user local drive or network drive. Our organization still primarily uses Outlook desktop clients, due to the limitations in the web client. So if someone receives an email with an attachment, they should have the ability to upload directly from the email to SharePoint Online. This can be done with view in file explorer. Outlook 365 desktop client has the ability to upload email attachments to Office 365 groups, but that feature does not show all the available Office 365 groups. I'm a member of every 365 group in our organization. When I use the 365 Outlook upload attachment option I can only see 6 of several dozen groups. Not very useful. 

 

You simply can't kill off something that works and provides value to people unless you have an alternative that works. Currently there is no alternative that works.

I have a MFC application that I have maintained for a number of years and I have two specific areas of concern:

 

  1. I use the CHtmlView web browser control for display reports in my software. I do allow the user to also preview externally in any installed browser but fundamentally for the mechanics of my editor it uses the internal CHtmlView browser. Is this going to still be supported or upgraded so that it does not break? Or will it be unaffected? I need a working way forward please. This is important to me and my users.
  2. I use the standard Windows 10 mechanism for transforming XML / XSL files into HTML (which is used with my editor). I assume that this functionality will still work?

I am not sure of where to ask these questions so I hope that someone can officially put my mind at rest. Please note that I do not use Office 365, although I do use the Microsoft Graph API to work with online calendars.

 

I hope for clarification soon.

 

Kind Regards

Microsoft

I'd like to share a note of clarification (@Bruno_A_Vieira@DanCooperstock@chuckie300) - This announcement does not affect apps or add-ins that embed web content using a WebView or browser control based on Microsoft Edge Legacy (EdgeHTML) or IE11, such as UWP web apps or Office Add-ins, including WebBrowser OLE objects, CHtmlView, etc. These apps will continue to work as expected. Where appropriate, we encourage app developers to consider migrating to a solution built on the new Chromium-based WebView2 or Progressive Web Apps, which provide a more modern and secure embedding solution on Windows. We'll add this clarification to the blog post above as well.

 

@Richard_van_Nuland - At this time, we don't currently have a plan to add full developer tools support for IEMode, but we're investigating a number of options here. It would be very helpful to know more about your use case and requirements to help inform those investigations. I'm happy to put you in touch with our tools crew for a more detailed conversation if it would be useful. 

 

Thanks!

@Kyle Pflug Thanks. I am not aware of this new web browser control so I will look. Good to know that our existing coding will still continue to work. Will the new browser control support XML/XSLT transformations? You can put me in touch and I am happy to provide link to my website where the software application is. XML / XSL - CHtmlView are at the heart of the application (in MFC) and is in about 50 languages and used worldwide.

Occasional Visitor

@Kyle Pflug, thank you. My understanding is that the WebView2 doesn't support Design Mode, that we use. Please correct me if that is incorrect.

 

Also, is that usable as an ActiveX? Our programming is in PowerBuilder, not .NET, so we can't use controls that only have .NET versions.

 

In any case though, we still need to support users using Windows versions prior to Windows 10 (e.g. Windows 7 and Vista), because our users are small churches and charities that cannot always have the money to be up to date. So I'm not sure they would have Edge and thus the WebView2 control. 

Thanks.

IE11が使えなくなるため、統合認証のアプリはEdgeに持っていきたい。

しかしADFSを使っているとEdgeでは統合認証が動かない。

この記述には誤りがあった。

Edg/*”ではなく、"=~Mozilla/5.*Edg/.*"などの正規表現を使う必要がありそうだった。

やはり影響をまとめた資料は必要になると思われる。

App Assure特典でも仕方ないが、トラブル発生を待つのではなく能動的に準備していることは伝えてほしいです!

Is WebView2 going to be rolled into the built in VBA environment or is this another nail in the coffin of VBA personal development?

@DanCooperstock This post is about the M365 team dropping support for IE from its web sites. M365 team is under the Office division, it has no say over how long IE itself gonna be supported (that is the job of the Windows team). This post affirms that IE would continue to be supported for the duration of Windows lifecycle. 

 

@Edward_B same goes for SCCM, the Windows Server team isn't part of the Office division either. They are also not in the same division of Windows Client. They make independent decisions on how long they support IE on its web sites. Check with the team. 

 

To other visitors who are misled by media, no, this isn't Microsoft killing IE. Read the blog title.

I have Microsoft Office Home + Student RT 2013, Outlook 2013 RT + One Note RT 2013 that came permanently installed with my Surface 2. Can I still continue to use these once support for IE 11 ceases, my Surface 2 is the perfect tablet for me. With the Splashtop Free app, I am able to connect to my iMac running El Capitan which makes my Surface 2 the complete laptop/tablet experience for me. Thanks.

"we want to be clear that IE 11 isn’t going away"

"Internet Explorer 11 is a component of the Windows operating system and follows the Lifecycle Policy for the product on which it is installed."

 

Can you confirm that iexplore.exe will remain available and the way it works will remain as long as Windows 10 is supported?

Or does it depend on a version of Windows10?

Will we be able to use iexplore.exe (for legacy webapps) on versions 20xx of Windows10?

For how long? For the remaining versions of Windows10?

Hi @K1K-1670 ,

 

Thank you for your question! Microsoft 365 apps and services will no longer support IE 11 after the listed dates. The products you listed are client apps and are not affected by this change.

Frequent Visitor

Eric, So to be clear, my free install of MS Office RT 2013, will continue to work as it does now? Also since IE 11 is a software component of Windows 8.1 RT, will it continue to work as well, I notice when I go to certain sites eg: Twitter, I can't login because Twitter no longer supports IE 11, but most sites load well. As I was mentioning with the free Splashtop App from the Windows Store, I can run my iMac desktop with El Capitan on my Surface 2 with little or no lag because of the Tegra 4 processor, so I can use Waterfox or Safari as my browser. Even You Tube runs normally. As long as these factors continue to function, I am getting more from my Surface 2 than I thought possible. Thanks, Ken.

Just to clarify if I issue teams invites to several of my clients and some of them do not use Edge and still operate under IE, will they be able to access the teams invites and still join our meetings?

So when with the desktop apps actually drop Internet Explorer for rendering web content.

 

MFA login cannot use a security key from office because it doesn't support FIDO2

Addins cannot run Blazor Client Side

Occasional Visitor

As the article and many comments make clear:

Internet Explorer 11 is not going anywhere. It will remain for as long as Windows 10 remains.

There is new API they have made available for desktop apps to use the (new) edge viewer but it is is beta stage. So I am not touching it for now.

In short, no desktop app will break for the life of windows 10.

 

That is my understanding.
