Why move-mail-message needs a policy

Moving a mail message changes its folder location but is reversible—the message can be moved back to its original folder or retrieved from the target folder. This is a write operation that modifies metadata (folder assignment) rather than destructive deletion. The scope is limited to a single message and does not create financial obligations or execute arbitrary code.

From the tool's definition Tool name 'move-mail-message' and description 'Move a mail message to a different folder' indicate modification of message state/location within Outlook.
