Safe Domain Clarification Needed

MVP

Hi All,

 

For the Business Standard MS365 subscription plan, can a user add a safe domain to the Safelist? For example, if a user adds the domain @abc.com to the safe list, everyone with this domain should be considered a safe sender. Right? Or does the user have to include all sender's email addresses?

I thought it was possible until I read Overview of the Junk Email Filter (microsoft.com)

It states in part, By design, safe domains are not recognized by default in Exchange Online or Exchange Online Protection.

 

The screen below shows the syntax for adding both sender & domain, so now I am confused. Personally, I have added several domains to the safe list and am second-guessing if it is actually working.

As a best practice, I know that users should not add major host domains, like outlook.com, gmail.com, yahoo.com, etc., to the safe list.  But my client was asking about his partner's firm.

Any update on this as I too am confused by the wording on that article.

I did not get any response or clarification.

 

I do know you can block a domain but it is still unclear if I can add the domain to the safe list. 

I will do some more investigating over the next several weeks.
