The University owns the computer account. You own any electronic mail and files in your account. You may share them with others by setting the proper file permissions. You may NOT give your password to someone else so they can access your files. However, it is not possible to put disk quotas on all of the common or shared disk space.
Mail is stored in individual inboxes before it is read.
All of the inboxes reside in a common or shared area of disk space. It is possible for mail to be delayed or lost when this area of disk space fills up. You should save any mail that you wish to keep in mail folders, not your inbox. Unfortunately, a few people abuse this and have extremely large inboxes. CIS regrets that it may be necessary to delete any unduly large inboxes without warning.
