TITLE   :XADM: How to Modify Outlook LDAP for Foreign Systems
PRODUCT :Microsoft Exchange
PROD/VER:winnt:5.5
OPER/SYS:
KEYWORDS:exc55

======================================================================
-------------------------------------------------------------------------------
The information in this article applies to:

 - Microsoft Exchange Server, version 5.5 
-------------------------------------------------------------------------------

SUMMARY
=======

Exchange Server allows you to set up a Lightweight Directory Access Protocol
(LDAP) referral to foreign systems. Microsoft Outlook LDAP referral returns the
Simple Mail Transfer Protocol (SMTP) address for the foreign system by default.
In some cases, you may need to have Outlook return a different value from the
foreign system.

By default, the LDAP service (Ol98ldap.exe) client returns only SMTP addresses.
You can modify the Mapisvc.inf file on any computer with the LDAP service
installed to return an LDAP-enabled value from an LDAP server.

MORE INFORMATION
================

To modify the Mapisvc.inf file:

1. Quit and log off from Outlook 98 or Outlook 2000.

2. Locate the Mapisvc.inf file.

For Outlook 98

On a computer running Microsoft Windows NT, it is located in the Winnt\System32
folder.

On a computer running Microsoft Windows 95 or Microsoft Windows 98, it is located
in the Windows\System folder.

For Outlook 2000

On a computer running Windows NT, it is located in the Program Files\Common
Files\System\Mapi\1033\Nt folder.

On a computer running Windows 95 or Windows 98, it is located in the Program
Files\Common Files\System\Mapi\1033\95 folder or the Program Files\Common
Files\System\Mapi\1033\98 folder.

3. Locate the EMABLT section in the Mapisvc.inf file.

4. Locate and change the following two entries:

   6605001e=[Title]
   6606001e=[Value]

The Title will be the column header that LDAP displays in the results window.

The Value is the value name that is being pulled from the LDAP server on the
foreign system.

   Example:

   6605001e=Unix X400
   6606001e=mhsORAddress

Would return the X400 address from a Unix MHS Server.

5. Start Outlook 98 or Outlook 2000 and add a new LDAP directory service in the
   Tools\Services\Add\Microsoft LDAP folder.

NOTE: The new Mapisvc.inf file settings do not take effect until a new LDAP
service is added to the profile. If an LDAP directory service was added to the
profile before the change was made in the Mapisvc.inf file, you must remove the
LDAP service and add it again.
