ldap error

    I am having great difficulty trying to resolve an ldap issue that my users
    are having in outlook 2007. We are presently in the process of upgrading from
    office 2000 to office 2007. The problem did not occur in outlook 2000. The
    problem is:

    In outlook 2007, if a user does an ldap search on approximately 6 or more
    users, and than tries sending the message, a Microsoft LDAP error message
    pops up:

    "Error 52: Cannot connect to internet directory service (LDAP) server
    fc.hwcdsb.edu.on.ca. First check your network connection. Than check your
    LDAP server settings: On the tools menu, click account settings, click the
    address books tab, click the directory name, then click Change or Remove to
    modify or delete the directory."

    I have googled the message, and there is next to nothing on this. There was
    something i found that said to remove the ldap entry for fc.hwcdsb.edu.on.ca.
    which is not an acceptable solution.

    Is there a difference in the way outlook 2007 handles ldap, than the way
    outlook 2000 handled it? Would anyone know how to get around this? I have
    checked the event log, on the workstations and on our exchange 2000
    server...there is nothing.

    fc.hwcdsb.edu.on.ca is a firstclass conferencing/email system. I have called
    there support, and they were unable to see any issues on that
    system.....which i believe since outlook 2000 does not have a problem.

    Any help would be appreciated.

  3. I wrote this before seeing your post that you intended to move the thread to
    this newsgroup from the .contacts newsgroup.

    The problem was actually first noticed when sending through a distribution
    list...which is why I had posted in contacts originally. After thinking about
    it awhile and viewing existing posts in contacts, I thought it would receive
    more attention in the general questions newsgroup(where more ldap type
    questions seem to be posted). My apologies for the confusion and no offense

    As an update, I did a fresh install of xp and office 2007....no other
    software. I joined the computer to our domain and logged in as a test user
    with an exchange account.
    I setup the ldap....same thing happened.....error 52.

    Another update:

    I have found that our fc server can log ldap messages...so i turned it on.
    Certainly enough I can see that outlook 2007 makes 5 times as many ldap
    connections as compared to outlook 2000. Outlook 2000 does the lookup once.
    Outlook 2007 repeats the lookups several times (5x most likely.) It does it
    initially when it is supposed to, than it does it again when you click the ok
    button and it does it as well when you click on send to send the
    message....(and 2 other times before sending)
    I can't understand why this would be this way.

    Ok....time for an update. Problem is not solved yet. I have contacted
    Microsoft. I'm communicating with Ashish from India. Basically I explained
    the problem....he connected to my computer and i showed him as well. He
    pretty much did everything i did to troubleshoot. He has asked me if i could
    open up an ldap port on our firewall for our server so they could test over
    the net, which i did(our server is not fc.hwcdsb.edu.on.ca on the web for all
    you hackers who are getting excited). I also gave them some accounts they
    could send test messages to as well. Ashish is apparently working with senior
    engineers to resolve this....all for $300. Hopefully i will here back from
    him on Monday with good news. I will give you another update on this soap
    opera at that time.
