   Q256986 Description of the Microsoft Windows Registry

SYMPTOMS
========

As a result of conversion problems, Microsoft Exchange Connector to Lotus
cc:Mail (CCMC) may hang, produce a Dr. Watson error, or produce mail messages
with incorrect information. This article explains how to identify the message
that is having conversion problems, and to troubleshoot the CCMC.

CAUSE
=====

Problems encountered during message conversion are the cause of these symptoms
of hanging, Dr. Watson, or producing messages with incorrect information.

WORKAROUND
==========

WARNING: If you use Registry Editor incorrectly, you may cause serious problems
that may require you to reinstall your operating system. Microsoft cannot
guarantee that you can solve problems that result from using Registry Editor
incorrectly. Use Registry Editor at your own risk.

Troubleshooting Steps
---------------------

1. Reduce the number of messages that the Exchange Connector to Lotus cc:Mail is
   converting. To do this:

   a. Start the Registry Editor (Regedt32.exe), and locate the following
      registry key:

   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeCCMC
   \Parameters

   b. Change these values:

   Maximum Number of Messages to Export <set to 0x00000001(1)>
   Default Setting 0X00000010(16)
   Maximum Number of Messages to Import <set to 0x00000001(1)>
   Default Setting 0X00000005(5)

2. Capture messages coming across the Exchange Connector to Lotus cc:Mail. If
   the message is being sent from cc:Mail, the message will be saved before
   conversion takes place. If the message is being sent from Exchange Server,
   the message will be saved after conversion has taken place. The saved
   messages can be viewed using Notepad in the Exchsrvr\Ccmcdata\Export.bak or
   Import.bak directories. The name of the saved messages will be Msgxxxx.ccm,
   where X is a random hexadecimal number. To capture the above-mentioned
   messages:

   a. Start the Registry Editor (Regedt32.exe), and locate the following
      registry key:

   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeCCMC
   \Parameters

   b. Change these values:

   Save a copy of the Exported files <set to 0X00000001(1)>
   Save a copy of the Imported files <set to 0X00000001(1)>
   Valid settings 0X00000000(0) and 0X00000001(1)

NOTE: After you change the above registry setting, the Microsoft Exchange
Connector for Lotus cc:Mail service should restart successfully.

After capturing and reviewing the converted messages, please contact Microsoft
Product Support Services.
