Solved Excel 2010 "File In Use" notification doesn't show

Hello!

We have shared folder on server that specific users can open it. In that folder there are bunch of excel files that they need to fill in. Problem starts when one user opens the document and starts filling the excel file, in that moment other user opens the same excel file but doesn't get the "file in use" notification. I have that problem for now only on one pc (win7, office 2010 standard + sp1). I tried to reinstall office 2010 and install all the updates but with no solution. Tried to delete all remaining Office folders but this also didn't solve the problem. Excel file on server is in 2003 format. On other pc with office 2010 standard upgraded from office 2003 professional i don't have that problem when opening the file, I receive "file in use" notification. Does anybody had similar problems and knows how to solve it? Thanks

Problem solved. Permissions from the main folder didn't inherit on child folder thus user could open specific file in child folder but couldn't get "file in use" notification. After readding user as domain admin problem was solved.

Can you please explain it more detailed
