IMAP Failover Connection For Office 365 (Optional)

If you are using an IMAP connection and Office 365 is unable to deliver journaled email to Proofpoint Essentials (via the O365 Connector), journaled messages are delivered to an Undeliverable Journal Mailbox. You can create an IMAP connection to Office 365 that, if this occurs, will retrieve and archive messages delivered to this mailbox.

IMAP settings for Office 365 are listed here. You will also need to know the Username and Password of the Undeliverable Journal Mailbox you specified when creating the SMTP connection for Office 365.

SMTP Connections

While an SMTP connection is disabled, Proofpoint Essentials will not accept remote journaling requests. As a result, use caution when disabling an active SMTP connection.

IMAP Connections

Before you enable an IMAP connection, you may want to test it to ensure that Proofpoint Essentials can successfully connect using the settings defined. To test the connection, click . The status icon changes to indicate that a test connection is being attempted. If the test is successful, the status indicator changes to green. If unsuccessful, it changes to red: hover over the icon to see the error response.
