Lookes like this problem is for all spaces on our server.
hen we try to save a file in any application, e.g. Excel , or save attachement as using Outlook. A file with same name is created before applciation can save it and then application will ask "File xxx already exists …. Do you want to repalce it? ". It hapens for all files even if they did not exists on the space before we tried to save it. It is as if applciation first tries to sabve and en empty file is created when it tries to search if such a file exists.

It sounds very strange, did any body had seen this kinda of behaviour before? and what we can do to fix it?
