One Exchange Account that Recieves All Emails?

Question

Team- a consultant once set up and Exchange email account that all other emails in the domain forward to- kind of a catch-all account that all emails go to. It's an extremely time-efficient way to grab lost emails, or show that certain emails were indeed sent, etc. Does anyone know how to set this up?

Answer 1

A Catch-all mailbox is generally used for catching messages that aren't sent to a real or valid user:

If you want ALL messages then:

A mailflow rule will do that

Create a mailbox ( and set the quota to a large value)
and BCC all messages to it.

Adjust as necessary

What about configuring the journaling? It can be used to record all or targeted email messages.

There are two journaling options:

1. Standard journaling: Journal all messages that are sent to and received by mailboxes on a specific mailbox database. To journal all messages in your organization, you need to configure journaling on all mailbox databases on all Exchange servers.
2. Premium journaling: Use journal rules to journal messages based on recipients (all recipients or specified recipients), and scope (internal messages, external messages, or all messages).
