This is more of an irritant than a problem…but every so often, when I attempt to open an Excel file (any Excel file) on my Company's network I sometimes get the Excel message “File in Use”. Normally, the messages indicates which user actually has the file open…as it should. However, sometimes the message does NOT indicate the name of any particular user. Over time, I have been able to determine that when Excel does not provide a name, it is because there is in fact – NO user who has the file open. Nevertheless, if I simply click the “Notify” button, in about 5 minutes Excel dutifully notifies me that the “File is now available for use”. I have never seen this happen to files not saved on my Company's network (although I don't usually save files to my local hard drive).
This phenomena began to occur when my Company (Ford Motor Credit) upgraded to Office 2010.
Does anyone have any idea why this might be happening?
