Frequently Asked Questions

What is the difference between safe senders and safe domains?

A safe sender applies to one specific email address (like user@example.com), ensuring only messages from that exact person bypass the junk filter. A safe domain whitelists an entire organization (like @example.com), allowing emails from anyone at that company to reach your inbox safely.

Why are emails still going to junk after I added them to Safe Senders?

If messages continue to route to the Junk Email folder, they might be failing server-level security authentication checks like SPF or DMARC. Additionally, your organization's IT administrator may have set up strict global spam filter policies that override personal safe sender lists.

How do I remove an email address from the Safe Senders list?

In Outlook on the web, navigate to Settings > Mail > Junk email, find the address under 'Safe senders and domains', click the trash can icon next to it, and save. On the desktop application, go to Junk > Junk Email Options > Safe Senders tab, select the specific address, and click Remove.
