Most GroupWise features are available in Caching mode, with the exception of subscribing to other users’ notifications.
Several users can set up their Caching Mailboxes on a single shared computer.
If 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.
If disk space is limited, you can restrict the items that are downloaded to your local mailbox. You can specify to get the subject line only or specify a size limit.
Your GroupWise administrator can specify settings that do not allow you to use Caching mode or that require you to use only Caching mode.
