TITLE   :XCLN: Internet Options Tab Missing from Send Options Dialog Box

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

 - Microsoft Exchange Server, versions 5.0, 5.5 
 - Microsoft Outlook 97, versions 8.0, 8.01, 8.02, 8.03 
 - Microsoft Exchange Windows 3.x client, versions 4.0, 5.0, 5.5 
 - Microsoft Exchange Windows 95/98 client, versions 4.0, 5.0, 5.5 
 - Microsoft Exchange Windows NT client, versions 4.0, 5.0, 5.5 
-------------------------------------------------------------------------------


SYMPTOMS
========

When you go to Properties of a message in any of the Microsoft Exchange clients
or Outlook clients and click Send Options, no Internet tab will appear on the
dialog box. Without this tab, the type of encoding format for attachments is no
longer configurable.

CAUSE
=====

Due to a registry limitation, the maximum number of message types (for example,
SMTP, MS, EX, X.400, and so on) that can be stored by any given client is
hard-coded to 16. If you have more than 16 unique message types, some of them
will not be downloaded to the client's registry. These message types are stored
alphabetically, and this problem is only seen when 16 message types
alphabetically come before SMTP. For example, if a Microsoft Exchange
organization has 16 unique custom message types that begin with the letter "F",
the SMTP option information will not be stored in the client's registry and the
Internet tab will not be shown in the Send Options dialog box.


RESOLUTION
==========

To resolve this problem, obtain the latest service pack for Exchange Server
version 5.5. For more information, please see the following article in the
Microsoft Knowledge Base:
