    Apparently phoenix thinks we have all the time in the world to search zimbra's wonderful forums. Just stating that if searching the forums fixed my problem, then why am I here?

    If phoenix believes that our questions have already been answered somewhere else, a post with 50 links on it would be better than spewing the same crap over and over and over again. "A forum search reveals these threads"

    What poor service. Do all people in UK treat each other this way?

    FYI, I have looked at several forms this morning with no real solution found.

    Tks Phoenix, i have try someway as on the others thread, but it cann't work on me.
    Unfortunately for me, i reinstall zimbra on my computer, but now it's running well.

    Now i have integrated Ldap authentification between zimbra and alfresco, and then i installed zimlet on in order to i can save my attachment from zimbra to Alfresco.

    Both of integration running well, i can save my attachment on Alfresco from Zimbra.
    But, when i try to get attachment from Alfresco Document, i cann't get it.

    i get error log like bellow on alfresco

    HTML Code:
