RemoteOnly: A shadow copy of the message should only be made on a server in a different Active Directory site.
PreferRemote: Try to make a shadow copy of the message in a different Active Directory site. If the operation fails, try make a shadow copy of the message on a server in the local Active Directory site.
The default value is PreferRemote.
The MaxRetriesForRemoteSiteShadow parameter specifies the maximum number of attempts to make a shadow copy of the message in a different Active Directory site. Valid input for this parameter is an integer between 0 and 255. The default value is 4.
