Outlook PST file error: In use by another person or program

Posted on 2009-02-10

I have an Outlook PST file (528 MB) created in 2006 that is locked.  The file is on a network, which I understand is not supported by MS, but that is where it is.  I am unable to rename or copy the file.  Outlook is not running.  The machine has been restarted multiple times, attempted to copy or rename the file before doing anything else.  I attempted to run SCANPST, received the same error.  I attempted to run Unlocker, received the same error.  I attempted to change owners and perms, successful, but received the same error.  I attempted to use Outlook Recovery Tool as well as SyncBack, both failed, same error.  I am working remotely on the issue, and the customer was unable to get the machine to start in Safe Mode, so that is out.  Outlook is not running, it is not running is Processes in Task Manager.  I turned off all extensions/add-ons as well.  Also get the error: The process cannot access the file because another process has locked a portion of the file.  This is a work stoppage for the customer, any direction would be much appreciated.

    Can the Admin for the network share disable the share, or reboot the computer/server hosting the share?

    I'd try and solve the problem locally first. Did you try and use Citrix GoTo Express( beta ends today I think) Pretty sure that this software will let you boot into safe mode with networking and still gain access to the computer.

    We cannot reboot the share, there are thousands of users on it- this is the NMCI network, the largest private network on the planet.  I am able to remote to cx machine without any trouble.  Have not tried Safe Mode, although I accessed the share from my admin machine and got the same error.

    If you have the same problem on anther computer( The Admin computer) then the problem is with the server.

    Can you list all the user's connected to the pst file, and disconnect them?

    I was able to locate the session of the file being used on the share and close that specific session.  That released the file.  Thanks.
