1.1 Glossary

This document uses the following terms:

Attachment object: A set of properties that represents a file, Message object, or structured storage that is attached to a Message object and is visible through the attachments table for a Message object.

calendar: A date range that shows availability, meetings, and appointments for one or more users or resources. See also Calendar object.

Coordinated Universal Time (UTC): A high-precision atomic time standard that approximately tracks Universal Time (UT). It is the basis for legal, civil time all over the Earth. Time zones around the world are expressed as positive and negative offsets from UTC. In this role, it is also referred to as Zulu time (Z) and Greenwich Mean Time (GMT). In these specifications, all references to UTC refer to the time at UTC-0 (or GMT).

Drafts folder: A special folder that is the default location for Message objects that have been saved but not sent.

flags: A set of values used to configure or report options or settings.

globally unique identifier (GUID): A term used interchangeably with universally unique identifier (UUID) in Microsoft protocol technical documents (TDs). Interchanging the usage of these terms does not imply or require a specific algorithm or mechanism to generate the value. Specifically, the use of this term does not imply or require that the algorithms described in [RFC4122] or [C706] must be used for generating the GUID. See also universally unique identifier (UUID).

handle: Any token that can be used to identify and access an object such as a device, file, or a window.

Hypertext Markup Language (HTML): An application of the Standard Generalized Markup Language (SGML) that uses tags to mark elements in a document, as described in [HTML].

Inbox folder: A special folder that is the default location for Message objects received by a user or resource.

Mail User Agent (MUA): A client application that is used to compose and read email messages.

Message object: A set of properties that represents an email message, appointment, contact, or other type of personal-information-management object. In addition to its own properties, a Message object contains recipient properties that represent the addressees to which it is addressed, and an attachments table that represents any files and other Message objects that are attached to it.

message store: A unit of containment for a single hierarchy of Folder objects, such as a mailbox or public folders.

Multimedia Messaging Service (MMS): A communications protocol that is designed for messages containing text, images, and other multimedia content that is sent between mobile phones.

Multimedia Messaging Service (MMS) object: A Message object that represents a Multimedia Messaging Service (MMS) message in a message store.

named property: A property that is identified by both a GUID and either a string name or a 32-bit identifier.

plain text: Text that does not have markup. See also plain text message body.

property ID: A 16-bit numeric identifier of a specific attribute (1). A property ID does not include any property type information.

reminder: A generally user-visible notification that a specified time has been reached. A reminder is most commonly related to the beginning of a meeting or the due time of a task but it can be applied to any object type.

remote operation (ROP): An operation that is invoked against a server. Each ROP represents an action, such as delete, send, or query. A ROP is contained in a ROP buffer for transmission over the wire.

ROP request: See ROP request buffer.

ROP response: See ROP response buffer.

rule: A condition or action, or a set of conditions or actions, that performs tasks automatically based on events and values.

Sent Items folder: A special folder that is the default location for storing copies of Message objects after they are submitted or sent.

Short Message Service (SMS): A communications protocol that is designed for sending text messages between mobile phones.

SMS object: A Message object that represents a Short Message Service (SMS) message in a message store.

special folder: One of a default set of Folder objects that can be used by an implementation to store and retrieve user data objects.

stream: A flow of data from one host to another host, or the data that flows between two hosts.

Unicode: A character encoding standard developed by the Unicode Consortium that represents almost all of the written languages of the world. The Unicode standard [UNICODE5.0.0/2007] provides three forms (UTF-8, UTF-16, and UTF-32) and seven schemes (UTF-8, UTF-16, UTF-16 BE, UTF-16 LE, UTF-32, UTF-32 LE, and UTF-32 BE).

MAY, SHOULD, MUST, SHOULD NOT, MUST NOT: These terms (in all caps) are used as defined in [RFC2119]. All statements of optional behavior use either MAY, SHOULD, or SHOULD NOT.
