Zimbra Upgrade to 8.8.15 issue with Chat

  • If you upgrade to ZImbra 8.8.15 you might notice an issue as below and with the following prompt.

    Unknown command sent to server: ZxChatReques


    To fix this, run the following on the Zimbra Server Terminal as root and then as Zimbra user:
    Move the old Zimbra Chat Java File

    mv /opt/zimbra/lib/ext/openchat/zal.jar /tmp

    Copy the Chat Java File

    cp -rp /opt/zimbra/lib/ext/zimbradrive/zal.jar /opt/zimbra/lib/ext/openchat/zal.jar

    Login as Zimbra User

    su - zimbra

    Restart the Mailbox Service

    zmmailboxdctl restart

    Then Chat works
