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.

blind carbon copy (Bcc) recipient: An addressee on a Message object that is not visible to recipients of the Message object.

carbon copy (Cc) recipient: An address on a Message object that is visible to recipients of the Message object but is not necessarily expected to take any action.

contents table: A Table object whose rows represent the Message objects that are contained in a Folder 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).

delegate: A user or resource that has permissions to act on behalf of another user or resource.

display name: A text string that is used to identify a principal or other object in the user interface. Also referred to as title.

Embedded Message object: A Message object that is stored as an Attachment object within another Message object.

Folder object: A messaging construct that is typically used to organize data into a hierarchy of objects containing Message objects and folder associated information (FAI) Message objects.

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.

long ID (LID): A 32-bit quantity that, in combination with a GUID, defines a named property.

mailbox: A message store that contains email, calendar items, and other Message objects for a single recipient.

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.

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

primary recipient: A person for whom a message is directly intended.

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

property name: A string that, in combination with a property set, identifies a named property.

public folder: A Folder object that is stored in a location that is publicly available.

recipient: An entity that is in an address list, can receive email messages, and contains a set of attributes (1). Each attribute has a set of associated values.

recurrence pattern: Information for a repeating event, such as the start and end time, the number of occurrences, and how occurrences are spaced, such as daily, weekly, or monthly.

recurring task: A series of Task objects that are described by a recurrence pattern.

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.

restriction: A filter used to map some domain into a subset of itself, by passing only those items from the domain that match the filter. Restrictions can be used to filter existing Table objects or to define new ones, such as search folder (2) or rule criteria.

Rich Text Format (RTF): Text with formatting as described in [MSFT-RTF].

ROP request: See ROP request buffer.

tagged property: A property that is defined by a 16-bit property ID and a 16-bit property type. The property ID for a tagged property is in the range 0x001 – 0x7FFF. Property IDs in the range 0x8000 – 0x8FFF are reserved for assignment to named properties.

task acceptance: A Message object that is used to convey acceptance of a task assignment.

task assignee: A user to whom a task has been assigned.

task assigner: A user who assigns a task to another user.

task communication: Collectively, a task request, a task acceptance or task rejection, and a task update.

Task object: A Message object that represents an assignment to be completed.

task owner: The user who is responsible for updating a task. For unassigned tasks, the local user is the owner. For assigned tasks, the task assignee is the owner.

task rejection: A Message object that is used to convey the rejection of a task assignment.

task request: A Message object that is used to issue a task assignment.

task update: A Message object that is used by a task assignee to send task changes to a task assigner.

Tasks folder: A Folder object that contains Task objects.

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.
