[xwiki-users] Hyperlink in Word/Excel file to Xwiki page fail to open

Hi. We are running XE-2.1.1 over Glassfish and recently one of our end users reported that when he clicked on a hyperlink in a MS-Word document that pointed to a page in our XE instance, MS-Word indicated in the status bar that "Word is preparing to go to this link" and then reports an error "Unable to open http://example.com/xwiki/bin/view.... Cannot download the information you requested". The expectation is that clicking on the click should simply dispatch the URL to the default browser. The URL of course opens without issue in all browsers. We did some research and experiments and found out that the above error only shows up for URLs that are not world-readable i.e. those that need authentication. We read through the MS-KB article http://support.microsoft.com/kb/838028/ and believe that the Office-2003 app itself is doing/attempting to fetch the content of the URL. Does any one have a clue how to make Office2003 (Word, Excel, PPT, Visio etc.) to simply handoff the URL to the browser instead of doing anything fancier? I am posting this query on this forum because I suspect XE might also be involved in this because it must be responding to the "OPTIONS" command and participating in the MS Office Discovery Protocol. Thanks, Milind
