1.1 Glossary
This document uses the following terms:
action: A discrete operation that is executed on an incoming Message object when all conditions in the same rule are TRUE. A rule contains one or more actions.
Address Book object: An entity in an address book that contains a set of attributes, each attribute with a set of associated values.
address type: An identifier for the type of email address, such as SMTP and EX.
Appointment object: A Calendar object that has an organizer but no attendees.
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.
character set: The range of characters used to represent textual data within a MIME body part, as described in [RFC2046].
condition: A logical expression comparing one or more properties in all incoming Message objects against a set of clauses. This logical expression can evaluate to TRUE or FALSE.
contact: A person, company, or other entity that is stored in a directory and is associated with one or more unique identifiers and attributes, such as an Internet message address or login name.
Contact object: A Message object that contains properties pertaining to a contact.
Contacts folder: A Folder object that contains Contact objects.
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).
cyclic redundancy check (CRC): An algorithm used to produce a checksum (a small, fixed number of bits) against a block of data, such as a packet of network traffic or a block of a computer file. The CRC is a broad class of functions used to detect errors after transmission or storage. A CRC is designed to catch random errors, as opposed to intentional errors. If errors might be introduced by a motivated and intelligent adversary, a cryptographic hash function should be used instead.
distribution list: A collection of users, computers, contacts, or other groups that is used only for email distribution, and addressed as a single recipient.
email address: A string that identifies a user and enables the user to receive Internet messages.
EntryID: A sequence of bytes that is used to identify and access an object.
File Transfer Protocol (FTP): A member of the TCP/IP suite of protocols that is used to copy files between two computers on the Internet if both computers support their respective FTP roles. One computer is an FTP client and the other is an FTP server.
flags: A set of values used to configure or report options or settings.
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.
free/busy status: A property of an appointment that indicates how an appointment on the calendar of an attendee or resource affects their availability.
Global Address List (GAL): An address list that conceptually represents the default address list for an address book.
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.
Integrated Services Digital Network (ISDN): A high-speed digital technology that uses existing telephone lines to provide Internet access and digital network services.
Joint Photographic Experts Group (JPEG): A raster graphics file format for displaying high-resolution color graphics. JPEG graphics apply a user-specified compression scheme that can significantly reduce the file sizes of photo-realistic color graphics. A higher level of compression results in lower quality, whereas a lower level of compression results in higher quality. JPEG-format files have a .jpg or .jpeg file name extension.
Journal object: A Message object that represents an entry in a journal or log and adheres to the property descriptions that are described in in [MS-OXOJRNL].
little-endian: Multiple-byte values that are byte-ordered with the least significant byte stored in the memory location with the lowest address.
locale: A collection of rules and data that are specific to a language and a geographical area. A locale can include information about sorting rules, date and time formatting, numeric and monetary conventions, and character classification.
long ID (LID): A 32-bit quantity that, in combination with a GUID, defines a named property.
mail user: An Address Book object that represents a person or entity that can receive deliverable messages.
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.
multivalue property: A property that can contain multiple values of the same type.
one-off EntryID: A special address object EntryID that encapsulates electronic address information, as described in [MS-OXCDATA].
Personal Distribution List object: A Message object that contains properties pertaining specifically to user-created distribution lists.
point: A unit of measurement for fonts and spacing. A point is equal to 1/72 of an inch.
Portable Network Graphics (PNG): A bitmap graphics file format that uses lossless data compression and supports variable transparency of images (alpha channels) and control of image brightness on different computers (gamma correction). PNG-format files have a .png file name extension.
property ID: A 16-bit numeric identifier of a specific attribute. 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.
recipient: An entity that is in an address list, can receive email messages, and contains a set of attributes. Each attribute has a set of associated values.
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.
Simple Mail Transfer Protocol (SMTP): A member of the TCP/IP suite of protocols that is used to transport Internet messages, as described in [RFC5321].
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).
Uniform Resource Locator (URL): A string of characters in a standardized format that identifies a document or resource on the World Wide Web. The format is as specified in [RFC1738].
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.
