A non-SMTP gateway connection failure has occurred: The drop directory doesn't have the correct access permissions.


This Error event indicates that the Network Services user account does not have the correct permissions assigned to the specified Drop directory that is used by the specified Foreign connector.

Two items control the location of the Drop directory for each Foreign connector that is configured on a Hub Transport server:

  • 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 2010 installation folder. The default installation folder is C:\Program Files\Microsoft\Exchange Server\V14.

  • 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. The Drop directory that is specified by the DropDirectory parameter is not created automatically.
