I recently came across an issue with Internet Explorer 10 that causes problems with a number of web sites. It took a little over a week back and forth with Microsoft support before we were able to finally target it to the browser. I thought it was an issue with a particular clients Office 365 tenant so that left us chasing our tails for a bit.
The problem stems from the way that Internet Explorer 10 handles websites in compatibility mode. Internet Explorer 8 and 9 respected a meta property embedded in the head of the website. Microsoft products like CRM and SharePoint utilized this property to automatically force the page into compatibility mode without any involvement from the user.
<meta http-equiv="X-UA-Compatible" content="IE=8" />
Internet Explorer 10, however, seems to disable compatibility mode by default… a big step forward in terms of Microsoft’s commitment to web standards but a a step backwards when it comes to… well… compatibility.
As seen in the screenshot above Internet Explorer 10 is correctly identifying the Document Mode as “IE8 standards” however the Browser Mode is reading as IE10 which causes a number of issues. Everything from straight crashes in Dynamics CRM 2011 and the dreaded “An Unknown Error has occurred.” in SharePoint 2010 and SharePoint Online. This is because that IE10 defaults to only display intranet sites in Compatibility View.
So far I’ve found that this is a problem on the following Microsoft sites / products. My most recent issue was an error with SharePoint Online when trying to use target audiences. This is not an extensive list… just my short list.
- SharePoint 2010
- SharePoint Online
- CRM Dyanmics 2011
- CRM Dynamics 2011 Online
Resolution / Work Around
In order to fix this issue follow the steps below.
- Open Internet Explorer 10
- Press ALT
- Click Tools > Compatibility View Settings
- In the “Add this website” box add the following sites using the Add button
- Click Close
Now when you refresh the page you should see the Browser Mode correctly represented as Browser Mode “IE10 Compat View” and Document Mode “IE8 Standards”.
