Outlook Lost Mailbox Lock error

  1. Default Outlook Lost Mailbox Lock error


    I have 3 users accessing the same account from Outlook 2000/XP/2003, and
    they are getting a 'Lost Mailbox Lock' error whenever the automated
    send/receive kicks off. I've updated to the latest UW-IMAPD, with no
    improvement.

    My best guess is that when User 1's Outlook is holding on to the IMAP
    connection for the mail account, and User 2's Outlook logs in to the
    same account, it kicks User 1 off, and Outlook complains. I have read
    that converting to a user-based mbox system can help (mailboxes are
    currently in the spool), I'm not sure it will have any effect.

    Can someone tell me either how to configure Outlook to release the IMAP
    connection when it's idle, or how to make the server play nice with
    multiple user accounts? Or, if I'm way off base, feel free to set me
    straight. Thanks in advance.

    The UW-IMAPD server, in its default configuration, does not allow the same
    folder to be opened by multiple clients at the same time.

    As long as multiple clients attempt to open the same mbox folder, at the
    same time, this error will continue to occur.

    The only thing you can do is convert the mail folders to the mbx format, on
    the server. This is a UW-IMAP-specific custom mail format that allows
    concurrent access. You will find some documentation in the UW-IMAP package
    with further information.
