ldap error

[Paul]

Hello;

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.
Thx.
Paul

Please don't multipost.

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
taken.

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....tried running outlook 2007 in safe mode. Problem still
happens.

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.
