  • Can not access local Ost file.

    To whom it migth concern.
    I have a user that is receiving the following message:
    "The file d:\"user"\Outlook.ost is in use and could not be accessed. Close
    any application that is using
    the file, and try again."
    The user has a e-mail box size on our Exhange 2003 server 1.6 GB.

    I do not kwnow how big the local *.ost is.
    The user is running Windows XP, with all service packs and Office 2003.

    Looking forward to find a solution for this problem.

    Thank you in advance.

    user may have several copies of outlook open.

    my first instinct would be to (laugh it up) reboot the OS and see if the file handle is released.

      If rebooting doesn't work then you can simply delete the OST file and it should resync with the Exchange server.

        Do they really need the OST???

        Do they ever work offline???

        My first instinct would be to remove cached mode for a bit and delete any OST files.

        Next i'd be looking at the format that the OST file is created in as depending on that format it will have either a 2GB limit or a 20GB limit.

        Then i'd be asking the user to archive some email to reduce the size of their mailbox.

          IIRC, cached mode is needed for the junk folder and full text searching to work effectively
          Not necessarily an argument to have it, but worth throwing into the ring
