Hi thanhtien19,

To block emails from a specific domain, you can follow these steps:

- Open the Exchange Admin Center (EAC) and navigate to the mail flow section.
- Create a new rule (+).

- Choose Limit messages by sender or recipient
- Add the condition “The adress from the sender correspodents...” and specify the exact domain you want to block (for example, @gmail.co).

This rule will block all emails sent from the specified domain.

      Use /(.co$) regex to block TLD 

      /(.today$)

      /(.live$)

      /(.life$)

      /(.world$)

      /(.ltd$)

      /(.co.nz$)
