In GroupWise, Offline mode is know as Caching mode. Caching mode stores a copy of your network mailbox, including your messages and other information, on your local drive. This allows you to use GroupWise whether or not your network or Post Office Agent is available.
Click the Mode Selector icon, then click Caching.
When you are asked to restart GroupWise, click Yes.
When GroupWise restarts, you are in Caching mode.
For more information, see Section 11.0, Caching and Remote Modes.
