Browser Compatibility with SharePoint 2010

SharePoint 2010 Browser Support

SharePoint Server 2010 supports several commonly used Web browsers. However, certain Web browsers might cause some SharePoint Server 2010 functionality to be downgraded, limited, or available only through alternative steps. In some cases, functionality might be unavailable for noncritical administrative tasks.

As part of planning your deployment of SharePoint Server 2010, we recommend that you review the browsers used in your organization to ensure optimal performance with SharePoint Server 2010.

Key planning phase of browser support

Browser support is an important part of your SharePoint Server 2010 implementation. Before you install SharePoint Server 2010, ensure that you know which browsers SharePoint Server 2010 supports. The information in this topic covers the following areas:

  • Browser support levels
  • Browser details
  • Browser compatibility for publishing sites
Browser support levels
Browser support for SharePoint Server 2010 can be divided into three different levels, as follows:
  • Supported

    A supported Web browser is a Web browser that is supported to work with SharePoint Server 2010, and all features and functionality work. If you encounter any issues, support can help you to resolve these issues.

  • Supported with known limitations

    A supported Web browser with known limitations is a Web browser that is supported to work with SharePoint Server 2010, although there are some known limitations. Most features and functionality work, but if there is a feature or functionality that does not work or is disabled by design, documentation on how to resolve these issues is readily available.

  • Not tested

    A Web browser that is not tested means that its compatibility with SharePoint Server 2010 is untested, and there may be issues with using the particular Web browser. SharePoint Server 2010 works best with up-to-date, standards-based Web browsers.

Browser details
You should review the details of the Web browser that you have or plan to use in your organization to ensure that the Web browser works with SharePoint Server 2010 and according to your business needs.

Internet Explorer 6 (32-bit)

SharePoint Server 2010 does not support Internet Explorer 6 (32-bit). If you use publishing sites, see the "Browser compatibility for publishing sites" section in this article.

Browser compatibility for publishing sites
For publishing sites, the Web Content Management features built into SharePoint Server 2010 provide a deep level of control over the markup and styling of the reader experience. Page designers can use these features to help ensure that the pages they design are compatible with additional browsers, including Internet Explorer 6, for viewing content. However, it is the page designers’ responsibility to create pages that are compatible with the browsers that they want to support.

A standards-based browser, such as Internet Explorer 8 or Firefox 3.x, is required to author content.

ActiveX controls

ome of the features in SharePoint Server 2010 use ActiveX controls. In secure environments, these controls must be able to work on the client computer before their features will function. Some ActiveX controls, such as those included in Microsoft Office 2010, does not work with 64-bit browser versions. For Microsoft Office 2010 (64-bit), only the following controls work with 64-bit browsers:

  • ppslax.dll – Slide library and PowerPoint 2010 integration
  • name.dll – Presence information
