Apple iOS/iPadOS 16 must implement the management setting: not allow messages in an ActiveSync Exchange account to be forwarded or moved to other accounts in the Apple iOS/iPadOS 16 Mail app.

Description

<VulnDiscussion>The Apple iOS/iPadOS Mail app can be configured to support multiple email accounts concurrently. These email accounts are likely to involve content of varying degrees of sensitivity (e.g., both personal and enterprise messages). To prevent the unauthorized and undetected forwarding or moving of messages from one account to another, Mail ActiveSync Exchange accounts can be configured to block such behavior. While users may still send a message from the Exchange account to another account, these transactions must involve an Exchange server, enabling audit records of the transaction, filtering of mail content, and subsequent forensic analysis.
