As discussed here but not resolved http://social.technet.microsoft.com/Forums/en-US/excel/thread/fc470dd1-70df-4bad-98db-3d94a68206c7. On opening a 2003.xls fle that contains linked cells to a network location the link paths are changed to the current local users appdata path. This really is an issue for us, we are a large coporate user with thousands of linked workbooks often with links to several other workbooks, it's not really an acceptable solution to have to manually update the links each time a 2010 users opens an existing 2003 doc.
Can anybody offer a solution?
