Running Exchange 2003 with Outlook 2007 clients.  A group mailbox is receiving an error "Cannot open this item. Unknown Error" when trying to open email messages from Outlook.  Some messages open, some do not; there does not seem to be a pattern  to the emails that will not open.  Could use assistance troubleshooting.  Thanks.

    Check this once.
    Also can you check event viewer once and post errors, if any.

    hi, are you using cache mode? Try to disable cache mode and remove outllok.ost file in the user profile app data and so on...

    This will prob. Work if you can read messages correctly in owa

    Not using GFI mail security, this problem is on multiple client machines, not using cached mode.

    start > run > cmd
    navigate to exchange / bin directory.

    run eseutil / mh <path to priv1.edb>
    Check the shutdown state

    try out eseutil switches and see if you can spot something

    Try the following steps.
    Archive the mails using Exmerge
    Delete the mailbox
    Create a fresh mailbox on a different database if you have one
    Exmerg the PST back to the new mailbox.

    Seems some kind of corruption.

    Good luck
