IMPORTANT: This article contains information about editing the registry. Before you edit the registry, make sure you understand how to restore it if a problem occurs. For information on how to do this, view the "Restoring the Registry" online Help topic in Regedit.exe or the "Restoring a Registry Key" online Help topic in Regedt32.exe.



SUMMARY
This article discusses the registry entries for modifying the polling frequencies of the Microsoft Exchange Connector for Lotus cc:Mail.

CAUTION: The default settings have been set to give the cc:Mail Connector optimal performance. Please do not change these settings unless absolutely necessary. Modifying these settings could adversely affect the performance of the connector.



MORE INFORMATION
Several registry values control when and how the cc:Mail connector service activates and the amount of processing it performs.

WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall Windows. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

For information about how to edit the registry, view the "Changing Keys And Values" online Help topic in Registry Editor (Regedit.exe) or the "Add and Delete Information in the Registry" and "Edit Registry Data" online Help topics in Regedt32.exe. Note that you should back up the registry before you edit it.

Registry entries that control the connector are found in the following registry location:   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeCCMC\ Parameters The entry for the polling interval at which the Export.exe program runs is:   Second to wait before EXPORT and the default is 15 seconds.

The entry for the polling interval at which the Import.exe program runs is:   Second to wait before IMPORT and the default is 15 seconds.

The entry for the number of messages to request from cc:mail Export for each activation is:   Maximum number of messages to EXPORT and the default is 16.

The entry for the number of messages to Import to cc:mail on each Import activation is:   Maximum number of messages to IMPORT and the default is 5.

By default, the Connector service checks the Import directory and the cc:mail post office every 15 seconds, in accordance with the settings in the first two registry entries above (Second to wait before EXPORT and Second to wait before IMPORT). If there are messages awaiting delivery, the connector service requests 16 or 5 messages to be delivered, in accordance with the second set of registry entries (Maximum number of messages to EXPORT and Maximum number of messages to IMPORT).

If the maximum number of messages processed during the Import or Export session is equal to the registry value, the server immediately processes another session. By immediately processing again when the maximum number of messages are present, the connector can continually move messages when there is a backlog. If the number of messages is less than the default value, no additional processing occurs until the time interval expires.
