Configuring SharePoint Protocol for Online Editing

The following issues are known for configuring the SharePoint Protocol for Online Editing.

  • There is a known issue where Online Editing is not available using the 64-bit version of Internet Explorer. See Plan browser support (SharePoint Server 2010) for more information.
  • It is important to set the and vti.server.external.port properties in the file to the externally resolvable host and port name that SharePoint clients will communicate with. These properties default to the host machine's local name and port 7070, respectively. These values are used by Share to generate the Edit Online link, which opens the document using the SharePoint module.
  • There is a known issue with Office 2003 and 2007 Office documents opening as read-only in Internet Explorer for all versions before Vista SP1.

    Refer to the knowledge base article 870853 on the Microsoft website to enable the Online Editing functionality.

  • To use Online Editing on Windows 7, you must set BasicAuthLevel in the registry.

    Basic authentication is disabled on Office 2010 by default. To enable it, create or edit the following registry key: HKCU\Software\Microsoft\Office\14.0\Common\Internet: BasicAuthLevel=2.

    Alternatively, use Pass-through or Kerberos authentication.

  • You can not use Online Editing for an MS Office document whose path length is greater than 255 characters. This is due to a limitation with the Windows file redirector.
