A catchall mailbox is a mailbox to which any email not destined for a specific mailbox is delivered. For example, if someone were to send an email to firstname.lastname@example.org, it would get routed to a catch-all address for the example.com domain. If no catch-all mailbox had been set up, the email would simply be returned to the sender with an error message.
Microsoft Exchange has no native support for catch-all mailboxes, but the freeware Netwrix Catch-All Mailbox Configurator tool is a very easy way to configure a catch-all email with a couple of mouse clicks and without any custom scripts and tricky configuration steps. You just install this tool on your Hub Transport or Edge Transport Exchange Server and specify an email domain and e-mail address to which all uncaught mail should be forwarded.
