Replication Folder Conflict Age Limit for a public folder store is non-default

[This topic is intended to address a specific issue called out by the Exchange Server Analyzer Tool. You should apply it only to systems that have had the Exchange Server Analyzer Tool run against them and are experiencing that specific issue. The Exchange Server Analyzer Tool, available as a free download, remotely collects configuration data from each server in the topology and automatically analyzes the data. The resulting report details important configuration issues, potential problems, and nondefault product settings. By following these recommendations, you can achieve better performance, scalability, reliability, and uptime.

The Microsoft® Exchange Server Analyzer Tool reads the following registry value to determine whether folder conflict aging has been modified from its default setting:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIS\<ServerName>\Public-<Public Folder GUID>\Replication Folder Conflict Age Limit

If the Exchange Server Analyzer finds that the Replication Folder Conflict Age Limit registry value is present and configured, a non-default configuration message is displayed.

When two users have edited and modified the same message in a public folder, the resulting saved messages are defined as being in conflict. This situation can occur when a simultaneous save occurs on the same public folder server, or if the message is edited on two servers that contain replicas of the folder. If no action is taken by the owners of the public folder within the period established by the conflict age limit, the conflict is resolved by the public folder store after the age limit has elapsed. The Replication Folder Conflict Age Limit registry value controls this age limit. Its value is the number of days that items in conflict are allowed to exist.

This article contains information about editing the registry. Before you edit the registry, make sure you understand how to restore the registry if a problem occurs. For information about how to restore the registry, view the "Restore the Registry" Help topic in Regedit.exe or Regedt32.exe.

To revert to the default configuration

  1. Open a registry editor, such as Regedit.exe or Regedt32.exe.

  2. Navigate to: HKLM\SYSTEM\CurrentControlSet\Services\MSExchangeIS\<ServerName>\Public-<Public Folder GUID>

  3. Delete the Replication Folder Conflict Age Limit registry value.

  4. Restart the Microsoft Exchange Information Store service for the change to take effect.
