electronic discovery (eDiscovery): A type of legal discovery that focuses on electronic (computer) communications and files.
email address: A string that identifies a user and enables the user to receive Internet messages.
embedded object: An object that is created by using one application and is hosted in a document that was created by using another application. Embedding an object, rather than inserting or pasting it, ensures that the object retains its original format. Users can double-click an embedded object and edit it with the toolbars and menus from the application that was used to create it. See also Object Linking and Embedding (OLE).
encapsulation: A process of encoding one document in another document in a way that allows the first document to be re-created in a form that is nearly identical to its original form.
encrypted message: An Internet email message that is in the format described by [RFC5751] and uses the EnvelopedData CMS content type described in [RFC3852], or the Message object that represents such a message.
endpoint: (1) A client that is on a network and is requesting access to a network access server (NAS).
(2) A network-specific address of a remote procedure call (RPC) server process for remote procedure calls. The actual name and type of the endpoint depends on the RPC protocol sequence that is being used. For example, for RPC over TCP (RPC Protocol Sequence ncacn_ip_tcp), an endpoint might be TCP port 1025. For RPC over Server Message Block (RPC Protocol Sequence ncacn_np), an endpoint might be the name of a named pipe. For more information, see [C706].
(3) A participant that uses the Microsoft Groove Dynamics Protocol, as described in [MS-GRVDYNM], to synchronize with a shared space. An endpoint is identified by the combination of an identity URL and a client device URL. Each endpoint maintains a copy of the data in a shared space.
(4) A communication port that is exposed by an application server for a specific shared service and to which messages can be addressed.
(5) A device that is connected to a computer network.
enterprise/site/server distinguished name (ESSDN): An X500 DN that identifies an entry in an abstract naming scheme that is separate from an address book. The naming scheme defines enterprises, which contain sites, and sites contain servers and users. There is no concrete data structure that embodies an ESSDN. Instead, an address book entry can contain an ESSDN as a property of the entry.
Entity: A type of DataClass that represents a type of business data object that is stored in a line-of-business (LOB) system and whose instances have a persistent EntityInstanceId.
entry ID: See EntryID.
EntryID: A sequence of bytes that is used to identify and access an object.
event: (1) Any significant occurrence in a system or an application that requires users to be notified or an entry to be added to a log.
(2) An action or occurrence to which an application might respond. Examples include state changes, data transfers, key presses, and mouse movements.
event notification: A message that is sent by a subscribed resource to its subscribers or implied subscribers, notifying them of an event on that resource.
Exception Embedded Message object: An Embedded Message object that contains the changes for an Exception object.
Exception object: An instance of a recurring series that differs from the rest of the recurring series, for example by start time.
extended rule: A rule that is added to, modified, and deleted from a server by using a mechanism other than standard rules, but is otherwise functionally identical to a standard rule.
external identifier: A globally unique identifier for an entity that represents either a foreign identifier or an internal identifier (2). It consists of a GUID that represents a namespace followed by one or more bytes that contain an identifier for an entity within that namespace. If an external identifier represents an internal identifier (2), it can be also called a global identifier.
external OOF message: An OOF message that is sent to external users.
