Outlook ldap issue

[Rich S.]

Hello all,

I am having an issue with Outlook 2003 making an ldap
query. The ldap service has been added in my messaging
profile. Whenever I make a query to my ldap server, I
receive the following error: MAPI_E_CALL_FAILED

I have applied the latest service packs for Office XP, and
found a knowledgebase article with a registry entry to
make. I made this modification and still receive the same
error.

However, when I use an Outlook 2000 client, the ldap query
works properly and returns the correct information. So, I
don't believe the issue is with my ldap server.

I'd appreciate any help/suggestions anyone can provide.

Thanks.
