Copies of some sent messages are stored in this folder. These are some of the messages automatically sent by the Information System and messages sent by the study department or teachers (if the teacher has indicated that the message is to be archived). Messages stored in Archived Messages do not count toward the mailbox size quota.
The folder cannot be manipulated (delete messages from it). The folder is used to prove or verify later that a particular message has been delivered to you and its exact content.
