Windows 7 Offline Files - Working online, but server copy of file does not lock.

Posted on 2011-10-20

Ok, so a Windows 7 client (User A) has a network folder marked as 'Available Offline'. They open a document within this folder while connected to the network and shown as working 'on-line'.

User B, who doesn't use offline files, is in the same office and opens the same file, with full write access. This means when User A opens the document, it didn't lock the server copy, even though the user was working 'on-line' and fully synchronised.

If User B opens the file first, the file takes longer to open for User A and they receive the 'this file is in-use' warning.

Anyone have any thoughts? This doesn't happen when the user with offline files has XP.

    Forgot to add that if User A opens a file that's not available offline, it locks exactly as it should on the server and User B receives the 'file in use' warning.

    This issue is repeatable, even on a different network, with new Windows 7 SP1 machines.

    Accepted Solution

    Incase anyone stumbles on this thread. The fix is to add the following registry entry on all Windows 7 machines...


    This stops Windows 7 machines from using the offline cached copy of a document when opening.
