Mailboxes are a container for inter-administrative processing services (EACAT Procedures), grouped by thematic, organic or functional areas, to which you assign a certain number of users. This is how users assigned to the mailbox can access, consult and edit all the procedures of the services.
Therefore, the mailbox system is designed to simplify the management of access to these services and improve internal organization, although it is optional and it is the manager of the entity who administers it (activates, creates, deactivates and deletes mailboxes).
