I have added the doc icons and MIME types to my SPS2003 farm and now it works properly with Office2007 documents, with the exception of 'protected' Excel files. In those cases where the Excel file contains a 'protected' worksheet, the user can
open the doc, unprotect the worksheet and make their edits. When they 'protect' the worksheet again and try to save the file, they get an alert that the destination file is 'read-only' and they must save it with a different name.
This only happens for 'protected' Excel 2007 docs residing on an SPS2003 site. Protected Excel 2003 documents work fine, as do unprotected documents. Any help y'all can be is greatly appreciated. I only have two users who are using
the protected worksheets, but they are the most vocal of my users.
