Microsoft Office SharePoint Server 2007 supports several Web browsers that are commonly used. However, there are certain browsers that might cause some Office SharePoint Server 2007 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 Office SharePoint Server 2007, we recommend that you review the browsers used in your organization to ensure optimal performance with Office SharePoint Server 2007.

Web browser support is divided into two levels: level 1 and level 2. Although administrative tasks on SharePoint sites are optimized for level 1 browsers, Office SharePoint Server 2007 also provides support for other browsers that are commonly used. To ensure that you have complete access to all the functionality, we recommend that you use a level 1 browser for administrative tasks.
Level 1 Web browsers take advantage of advanced features provided by ActiveX controls and provide the most complete user experience. Level 1 browsers offer full functionality on all SharePoint sites, including the SharePoint Central Administration Web site. Level 1 browsers are:
• Microsoft Internet Explorer 6.x (32-bit)
• Windows Internet Explorer 7.x (32-bit)
Level 1 browser support is only available for computers running the Windows operating system.
Level 2 Web browsers provide basic functionality, so that users can both read and write in SharePoint sites and perform site administration. However, because ActiveX controls are supported only in level 1 browsers and due to the functionality differences within different browsers, a different user experience might be provided and there could be some variances from the user experience from the level 1 browsers. Level 2 browsers are listed in the following table.
