Steps to whitelist an email address or a domain

Microsoft 365 provides a layer of protection for your email account which diverts suspected spam emails to a separate folder away from the Inbox.

But it is always a possibility that you want some of those emails to come to the Inbox.

 

To bypass SPAM filtering, such emails and domains can be whitelisted.

Here are the steps to whitelist an email address or a domain.

 

  1. Go to the M365 Security Portal -  https://security.microsoft.com/
  2. Expand Email & Collaboration in the sidebar on the left and navigate to Policies & rules > Threat Policies > Anti-spam inbound policy (Default)
  3. Scroll down and click Edit allowed and Blocked senders and Domains
  4. Add the email address or domain you wish to whitelist
