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 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 system administrator can specify settings that do not allow you to use Caching mode or that require you to use only Caching mode.
