The Emergency Inbox service is for mail continuity. Users accessing this feature are able to use a web mail based mail feature while their mail server is down.

What It Does

Proofpoint Essentials will continue to try and check the customer's mail server, as per the standard set-up. As we are unable to relay the email from our system to the customer's server (as it is down), we are required by RFC to send a deferral notice to the sending mail server that we have been unsuccessful in delivering the email. As long as the customer's mail server is down, we will continue to send deferral messages for some time (we set 30 days) then bounce the message back to the sender. The customer's mail server should be repaired as soon as possible to not lose email.

Emergency Inbox provides access to email in the event that a user's mail environment is unavailable. Once this occurs Proofpoint Essentials automatically begins to spool mail for the affected domain and the Emergency Inbox will immediately show the spooled mail. Users are able to send new messages and reply to received messages. When an email is sent from Emergency Inbox it is treated like any outbound message. The email will show in another internal user’s Emergency Inbox.  Users are unable to see messages that were successfully delivered prior to mail delivery being impacted.

How To Access Emergency Inbox
