Gateway Address Routing Table (GWART): A list of values that specifies the address types that are supported by transport gateways.
ghosted: (1) A property that is not deleted by the server if the element is not included in a Sync <Change> request message. By default, elements that are not included in a Sync <Change> request are deleted from the store.
(2) See uncustomized.
ghosted folder: A folder whose contents are located on another server.
global counter: A 6-byte value that is incremented automatically. If a global counter is paired with a REPLID it forms a message ID (MID), folder ID (FID), or change number. If a global counter is paired with a REPLGUID it forms a global identifier.
global identifier: A form of encoding for an internal identifier that makes it unique across all stores. Global identifiers are a subset of external identifiers, and they consist of a REPLGUID followed by a 6-byte global counter.
Globally Routable User Agent URI (GRUU): A URI that identifies a user agent and is globally routable. A URI possesses a GRUU property if it is useable by any user agent client (UAC) that is connected to the Internet, routable to a specific user agent instance, and long-lived.
Graphics Interchange Format (GIF): A compression format that supports device-independent transmission and interchange of bitmapped image data. The format uses a palette of up to 256 distinct colors from the 24-bit RGB color space. It also supports animation and a separate palette of 256 colors for each frame. The color limitation makes the GIF format unsuitable for reproducing color photographs and other images with gradients of color, but it is well-suited for simpler images such as graphics with solid areas of color.
group header: A navigation shortcut that groups other navigation shortcuts.
