Microsoft Outlook Web: Add an Email Address to Safe or Blocked Senders and Domains

Safe or Blocked Senders and Domains

Safe Senders & Domains

There are times when you don't want messages from a specific person or domain (all senders from a specific domain, such as @mtsu.edu) to end up in your Junk Email folder. Messages from addresses or domains on the safe senders list won't get moved to your Junk Email folder or Quarantine.

Blocked Senders & Domains

You can block messages from specific email addresses or domains (all senders from a specific domain, such as @mtsu.edu) from reaching your inbox. When you add an email address or domain to your blocked senders list, Outlook automatically moves messages from that sender to the Junk Email folder or Quarantine.
