Inboxes and Outboxes act as approval gates in your SAP system for all SAP changes moving through the landscape.
When a change reaches an Inbox, an approval emails is sent automatically to the defined approver(s). The change will not import into the associated system until Inbox Approval is granted.
When a change reaches an Outbox, an approval emails is sent automatically to the defined approver(s). The change will not move out of the associated system until the Outbox approval is granted.
With giving an approval the defined analyzers for this control point are executed.
