I have installed office 2007 home and student on my computer but there are various versions being used on our server (about 10 computers). Recently, either the office suite or the server has seen fit to lock certain excel files tying them to either a specific computer or a very general "another user." In both cases, the files are not in fact being used by the other computers and we have even tried accessing them with all other computers off. We have been forced, because of time issues, to create a copy of the file for merging at a later date but this is not a long-term fix as I cannot move, edit, rename, or delete the original files nor can I manage the piles of temp files that are being created with each edit to the new copy. Office support wants to charge me three hundred dollars to trouble shoot this issue and maintains that it is not a microsoft office issue, but a server issue. Either way, I need to solve this problem but we cannot afford too pay $300! Do you have any knowledge pertaining to our problem? Any help would be much appreciated.
