MOM Rule Name

The non-SMTP gateway connection failed on the specified connector, because the file name for the Drop directory exceeds the system-defined maximum length.

This Error event indicates that the file name or path name of a message file that is located in the Drop directory is too long.

The maximum allowed length of a file path is 246 characters. The file path contains the following elements:

  • A single drive letter character
  • The colon character(":")
  • The backslash character("\")
  • The directory and subdirectory names
  • The backslash characters that separate the directory and subdirectory names

The maximum allowed length of a file name is 254 characters. The file name contains the following elements:

  • The file name
  • The period character (".") that separates the file name from the file name extension
  • The file name extension

The maximum allowed length of the full path is 259 characters. The full file path contains the following elements:

  • The file path
  • The file name

Two items control the location of the Drop directory for each Foreign connector:

  • The RootDropDirectoryPath parameter on the Set-TransportServer cmdlet. This option is used for all Foreign connectors that exist on the Hub Transport server. By default, the value of the RootDropDirectoryPath parameter is blank. This indicates the value of the RootDropDirectoryPath parameter is the Microsoft Exchange Server 2007 installation folder. The default Exchange Server 2007 installation folder is C:\Program Files\Microsoft\Exchange Server\
  • The DropDirectory parameter on the Set-ForeignConnector cmdlet. This value is set for each Foreign Connector that exists on the Hub Transport server. The value of the DropDirectory parameter must be a simple directory name. The value of the DropDirectory parameter cannot contain any absolute path information.

To resolve this error, do one of the following:

  • Shorten the names of the message files so that the combination of the message file names and the directory path is less than 259 characters.
  • Move the location of the Drop directory by using the RootDropDirectoryPath parameter on the Set-TransportServer cmdlet and the DropDirectory parameter on the Set-ForeignConnector cmdlet so that the combination of the message file names and the directory path is less than 259 characters. Changing the location of the Drop directory does not copy any existing message files from the old directory to the new directory. The new directory location is active almost immediately after the configuration change, but any existing message files are left in the old directory.
