Caching mode stores a copy of your Online mailbox, including messages and other information, on your local drive. You can use GroupWise whether or not your network or Post Office Agent is available. Because you are not connected to the network all the time, this mode cuts down on network traffic and has the best performance. A connection is made automatically to retrieve and send new messages. All updates are performed in the background so GroupWise is not interrupted. This mode requires that you have enough disk space on your local drive to store your mailbox. When you run Caching mode and Remote mode on the same computer, the same local mailbox (also called the Caching mailbox or Remote mailbox) can be used to minimize disk space usage. (For information about Remote mode, see Using Remote Mode.)
To use Caching mode, the client installation must be a standard installation, not a workstation installation.
Your system administrator can specify settings that do not allow you to use Caching mode or that require you to use only Caching mode.
