I have just completed a in-place upgrade from SharePoint 2007 to 2010 and everything completed successfully.

I have installed the Office WebApps and followed all the steps to enable Word, Excel and PowerPoint.

When I try an open a xlsx file form a Document List it returns this error message:

This workbook cannot be opened because it is not stored in an Excel Services Application trusted location.

To create an Excel Services Application trusted location, contact your system administrator.

I have checked the Trusted Location settings and the default is for the whole ShaprePoint server.

Opening Word docs work fine with the web version.

Have you read this post? http://www.sharepointedutech.com/2010/06/22/sharepoint-2010-cannot-open-workbook-because-its-not-stored-in-an-excel-services-application-trusted-location/

  • Thanks, the post refers to sites using SSL which we are not using. Another other thing is there is no event being logged, which is making it hard to debug.

    Any clues in the ULS logs?

I actually ran into this same error on a new installation (not upgrade). It also defaulted to the entire server as a trusted location. What I planned to try tomorrow is to go ahead and explicitly add the library to the trusted locations anyway. Perhaps you should try the same.
