MORE INFORMATION
Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall the operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.

By default, the overwrite permissions feature is enabled when you merge your dial tone database to a production database. However, you can use the KeepTargetFolderACL DWORD value to enable or to disable the overwrite permissions feature.

The KeepTargetFolderACL DWORD value is located in the following registry subkey:

Note If the RecoverMailbox subkey is not listed under MSExchangeAdmin, you must create this subkey.

If the KeepTargetFolderACL DWORD value does not exist, or if it exists but the value is 0, the merge process overwrites the permissions on the target folder. However, if the KeepTargetFolderACL value exists and has a nonzero value (such as 1), the permissions on the target folder are retained.
