Transport and journaling rules
Three related screens act on mail as it moves, and they operate at different scopes.
| Screen | Scope | Purpose |
|---|---|---|
| Transport Rules | The whole organization | Act on mail in transit |
| Mailbox rules | One mailbox | Act on that mailbox’s mail |
| Journaling Rules | The whole organization | Keep a copy for compliance |
Transport rules
Section titled “Transport rules”A transport rule inspects mail passing through the organization and acts on it — redirecting, blocking, or modifying it based on conditions you define.
Rules are evaluated in order, so the sequence matters as much as the rules themselves.
Common uses: blocking specific senders or attachment types, redirecting mail for a departed employee, adding routing for a specific domain.
Mailbox rules
Section titled “Mailbox rules”Server-side rules acting on a single mailbox. They run on the server, so they apply whether or not the user’s mail client is open — which is the difference between these and rules a user creates in Outlook.
Useful for functional mailboxes that need to sort or forward reliably without depending on someone being logged in.
Journaling rules
Section titled “Journaling rules”Journaling keeps a copy of messages for compliance. Where a transport rule changes what happens to mail, a journaling rule simply records it.
Consumer spaces
Section titled “Consumer spaces”Transport rules, mailbox rules, retention policy and the other policy screens are hidden for consumer spaces. Journaling rules are not — they remain available.
