When I try to open an Excel file already opened by another user, randomly it shows the username or not.

Hi all,

Hope you can help us with it.

- We have tested it from many computers and versions of Office (2007 and 2010).

- The file server is a Windows Server R2 updated to the latests patches.

- We have tested deactivating the antivirus both in the desktop machines and in the server.

- We can reproduce the problem easily: User 1 opens the excel, User 2 opens the same excel and shows the alert with the username. Both users close the excel file. Then user 2 opens the same excel, and then user 1 opens the same file, then appears "another user" instead of the username. We can interchange the order and happens the same.

Any idea?

Thanks!
