    Hi @Mohamed Bazaraa

    Does these external guests are in the same tenant?

    Based on my experience, Microsoft 365 will create a domain for you like contoso.onmicrosoft.com when you sign up with the service. If user want to have the account look like #ext#@Company portal .com, they could buy the domain or just follow the steps in Add your users and domain to Microsoft 365.
