Add a Sender to the Outlook Safe Senders List

Learn how to prevent legitimate emails from being marked as spam by adding senders to your Outlook Safe Senders list.

Overview

If a legitimate email is being blocked as SPAM, you can add the sender to your Safe Senders list. This ensures future messages from that sender are delivered to your Inbox.

At DMACC, email addresses labeled as SPAM are not globally whitelisted for security reasons. Each user must manage their own Safe Senders list.
