This chapter introduces messaging fundamentals. This information will allow you to understand the core features and concepts that the GroupWise client provides. You will then be able to use these core concepts to meet your various messaging needs as you work with and interact with the GroupWise client.
The GroupWise client can be run in three different modes (a mode is what defines how the GroupWise client functions). Each of the following three modes provides various benefits:
Each is discussed in the sections that follow.
Online mode is the default mode that the GroupWise client operates in when first loaded. When in online mode, your GroupWise client establishes a network connection with the GroupWise server. (The GroupWise server hosts a GroupWise post office, which your client actually connects to.) This session is always connected, and as you compose, read, or send items, the client communicates in real time with the GroupWise post office. Online mode depends on the GroupWise post office being accessible all the time. If the GroupWise post office becomes inaccessible, your client will lose its connection, and you will not be able to run the GroupWise client.
In cache mode, the GroupWise client loads and runs against a local copy of your mailbox. This means that when the GroupWise client is running in cache mode, it does not depend on the GroupWise post office being accessible 100% of the time. Cache mode implies that the GroupWise client does have a readily available connection to the GroupWise post office whenever it needs to connect. Therefore, the GroupWise client in cache mode can connect at any time and synchronize the local mailbox with the online mailbox. Such is the case when you send a message—it is sent immediately.
The benefit of cache mode is that your GroupWise client can continue to function and stay up even if the GroupWise server becomes temporarily inaccessible. When the GroupWise server is once again accessible, the GroupWise client automatically establishes a connection, and the user is not interrupted.
Remote mode is similar to cache mode in that the GroupWise client loads and runs against a local copy of your mailbox. In remote mode, however, the GroupWise client may not have a readily available connection to the GroupWise server whenever it needs to connect. Therefore, when in remote mode, the GroupWise client will queue up any outgoing mail and synchronize it only when a scheduled or manual Send/Retrieve operation is issued. Additionally, in remote mode, some features such as Proxy and Busy search are not available. Remote mode also allows you to have very granular control over what you choose to synchronize between your local mailbox and the online mailbox.
Identifying Your Client Mode
There are two ways to identify what mode the GroupWise client is running in. The first is to look under the Mailbox tab to see the mode currently in use.
Figure 3.1 shows the client in online mode.

The second way to identify the mode is to display the Main menu and then choose File, Mode. Then the current mode of the GroupWise client will be checked.
