Why is Office 365 ending support for Internet Explorer 8?
Over the next year and more, Office 365 will be making major investments in the browser experience, delivering new innovations of user experiences across email, messaging, collaboration and more for laptops, PCs, tablets and mobile devices. This innovation will rely heavily on HTML5, which not only includes support for the latest multimedia offered on the web, but is also designed to optimize experiences on low-powered devices such as the smartphones and tablets many of use for daily business today.
The first version of the HTML5 specification was published in 2008. It was a partial specification, and Internet Explorer 8, which was released in 2009, provided support for the nascent spec. Over the past five years, the entire software industry has focused innovation on HTML5 to deliver rich web experiences in a standard-based protocol—and Internet Explorer 8 doesn’t support any of the innovations made over the past five years.
To deliver the kind of rich mobile and touch experiences that users expect today, Office 365 needs to focus our innovation on modern browsers such as Internet Explorer 10.
Microsoft is making major investments in the Office 365 user experience in the browser, and these improvements require the functionality delivered by a more modern browser such as Internet Explorer 10.
How can I tell what version of Internet Explorer I'm using?
Choose the "About Internet Explorer" option in the Internet Explorer menus. This appears in an options and settings menu which, depending on the version you are using, may be a gear icon or appear under "Help" or "Options."
Why 8 April 2014?
Office 365 provides customers 12 months' notice of disruptive change under our Online Services Support Lifecycle. We announced Office 365 is ending support for Internet Explorer 8 on the System Requirements Wiki on 9 April 2013.
Also, Office 365 users with computers running Windows XP need a supported browser to connect to the service. Internet Explorer 8 is the highest supported version of Internet Explorer that runs on Windows XP, so we will continue to support Internet Explorer 8 until all support for Windows XP ends on 8 April 2014.
Will Internet Explorer 8 function as usual until 8 April 2014?
The user experience with Internet Explorer 8 may be compromised when sending and receiving email with Outlook Web Access or while using the Office Web Apps (such as Word, PowerPoint, Excel and/or OneNote), especially when used on Windows XP or with low-memory machines.
If this happens while using the Outlook Web App, you may want to use Outlook Web App Light. If you experience this with other Office Web Apps such as Word, PowerPoint, Excel and/or OneNote Web Apps, we recommend you use the desktop version of Office instead.
What does "end of support" mean?
If you have a technical problem with Office365 while using Internet Explorer 8 and would like to open a ticket with Microsoft support, you will need to reproduce the issue with a supported browser.
Will Internet Explorer 8 users be blocked from connecting to Office 365 after 8 April 2014?
No, Office 365 will not deliberately block Internet Explorer 8 users from accessing the service after 8 April 2014. But after that date, users connecting to Outlook Web App will only be able to use Outlook Web App Light.
My organization doesn't have any users on Internet Explorer 8, so why did I receive this email?
With Office 365, your users can check their email from any computer in the world: if you are confident your organization is using Internet Explorer 10 or Internet Explorer 9, you may have had users checking email from a home computer, or at an Internet Café while on vacation.
I need help upgrading my organization's users from Internet Explorer 8. Where should I go?
You can find a partner on the Office 365 Marketplace: just look under the Desktop competency.
My organization has web applications developed specifically for Internet Explorer 8. What can do we need to do to upgrade browsers?
Internet Explorer includes an application property that developers can use to tell Internet Explorer for what version of the browser the application was developed. Internet Explorer will use this property to render the application as expected.
If you purchased the web application in question, please contact the vendor from whom you purchased it. If you have a custom-built application, you can find a partner to help you on the Office 365 Marketplace. Just select Companies, and under Competency, select Software Development.
I just need a couple more months before upgrading from Internet Explorer 8. Is there a way to keep using Internet Explorer 8 for a little bit longer?
Office 365 will not support Internet Explorer 8 after 8 April 2014, and there is no way for us to extend the date for individual customers.

Does Microsoft not realize that neither IE 9 nor IE10 works well with 90% of the business applications that are being used! To force an upgrade to IE10 is giving us no alternative but to NOT use IE as a default browser. We have to use one of your competitors in order to conduct our daily business!
Given that some people have to access using machines that are outside of our control (e.g. client site internet booths), please can setting the From of emails be allowed from mobile Office365 and (please) / or Windows Phone 8 Outlook. Thanks, Gaz
It would appear that there is a conflict of dates as to when support is ending...
See here: onlinehelp.microsoft.com/.../ff652534.aspx (passed onto me by an MS OSS Team Manager - EMEA, Microsoft Online Services & Support EMEA)
See that the date is 1st Jan 2014 for IE8/Win XP SP3?
I agree with Gary Varga - we were upgraded last week and I have had to install a competitor's browser because IE8 wasn't cutting it. Now that no-one in my company is using IE8 on their XP machines, I cannot troubleshoot, but then competitor browsers are not subjected to Group Policy (well, some tie into IE's "Internet Connections" but that's about it...)
@Kevin and Stephen. I'm interested in the issues you're experiencing. Kevin, if you can PM me with details of the specific issues you're seeing with IE9/10 and your Line of Business Applications and, likewise, Stephen on IE8/XP with Office 365, we'll look into them.
Regarding the mismatch on dates, I believe there's an error on the Software Requirements page that I'm looking into.
I can tell you that you definitely don't want to use IE8 on XP to run OWA. I had to switch our XP users to Chrome or Firefox to make OWA usable.
I agree with @Kevin that sites are not working properly with IE10, and now Office365 admin functions are not working with IE11, nor are the Sharepoint sites. Our other business apps are very niche products and so I understand when they require me to remoteapp IE8 to function on win8, or that I can upgrade win7 machines past ie8, but when MS's own sites arent working with the latest browser its frustating.
When I asked for help at Microsoft Shiphol (The Netherlands), they tell me that they use Google Chrome to work smoother. So Microsoft experts prefer to not use any IE for working in webbased applications. This is crazy, don`t you think so?!
