You cannot access Word documents by using Outlook Web Access on a server that is running SharePoint Portal Server

You may not be able to access Microsoft Word documents by using Microsoft Outlook Web Access (OWA) on a server that is running Microsoft SharePoint Portal Server. This problem may occur if the path of the folder that contains the document contains more than 100 characters.

This problem occurs because the MAX_WEB_FOLDER_LENGTH attribute is defined with a set limit of 100 characters. After you apply this hotfix, the MAX_WEB_FOLDER_LENGTH attribute is defined with a set limit of 260 characters. The hotfix changes the limit to 260 characters because some earlier versions of Microsoft Office have a limit of 260 characters, and this new limit will work correctly with earlier versions of Office.

A supported hotfix is now available from Microsoft, but it is only intended to correct the problem that is described in this article. Only apply it to systems that are experiencing this specific problem. This hotfix may receive additional testing.
