Trend Micro Email Security provides Email Continuity against email loss in the event of a mail server outage. If your server becomes unavailable due to a crash or network connectivity problem, Trend Micro Email Security automatically transfers inbound traffic to a backup server until your server is back online.

On the End User Console, a continuity mailbox is available instantly and automatically, enabling you to have continued email access during an outage without requiring any action from IT. The continuity mailbox allows you to perform the following tasks:

  • Composing and sending messages

  • Viewing inbox messages

  • Replying to, forwarding and downloading messages

  • Checking sent messages

When using the continuity mailbox, pay attention to the following:

  • To compose a message or view a message's details, be aware that only plain text is supported. To avoid losing information such as pictures and links during parsing, it is recommended you download messages to your local system.

  • If you find "Compose" and "Sent Items" are grayed out in the continuity mailbox, contact your administrator to enable email sending in Email Continuity settings.
