One of the most common maintenance issues in a growing system is running out of disk space. In addition to sending messages, users tend to use GroupWise for all sorts of communication, such as transferring large files. Library documents created with Document Management Services (DMS) can use huge amounts of disk space. Archived library documents can also quickly use up disk space assigned to the post office, where space is usually limited.
You should let your users know about the archive and auto-delete features of GroupWise mail, or set Client Options in the GroupWise Administration Console to automatically archive or delete. See Setting Defaults for the GroupWise Client Options.
