Hi Stian Holthe,

Thank you for your response.

As you mentioned "We run on pure M365.

Is it anyway to make answers from people outside of my organization, sent to a distribution list, be rejected?"

If Office 365 global admin has disabled below or enabled any specific option, outside people cannot send or reply to DL.

I have provided official options and all the required information for your initial and second question description..

For my provided official document, could you share your vote/feedback so that more users can easily access the URL of your thread? Because many users are finding some official document and specific direction in this community by searching for the topic.

Your valuable cooperation will be greatly appreciated in the community. Thank you once again for your kind contribution.

    Hi, thanks for your reply. We run on pure M365.

    Is it anyway to make answers from people outside of my organization, sent to a distribution list, be rejected?

    Hi Stian Holthe,

    Thank you for connecting with us in the Microsoft community.

    According to your description, before moving forward, may I please know whether are you Office 365 global admin or end user person in your Microsoft 365 Business tenant organization?

    Also, may I please know whether your organization's environment is pure Microsoft 365 exchange online server or connected with Exchange On-Premise / Hybrid or Azure AD?

    ==================================================================================================

    I did not find above requested information in your case description.

    But I will provide the following information based on our support limits. Because, since we are from the Microsoft 365 Business/Education support team and provide potential address information for pure Microsoft 365 Business exchange online service related scenario.

    For your initial case description, if your organization's environment is associated with pure Office 365 exchange online server environment and if you are an Office 365 global admin person, initially I have found one official document about Create and manage distribution groups in Exchange Online | Microsoft Learn **** which discussing email delivery management topic for inside and outside organization for DL.

    Reply to All: If the external recipient uses "Reply to All," their response will be sent to both the distribution list and any individual email addresses included in the original email. This means all members of the distribution list will receive the reply.

    Reply to Sender: If the external recipient replies only to the sender (you), their response will be sent only to your email address and not to the distribution list.

    To ensure replies are sent to the entire distribution list, you might want to remind external recipients to use "Reply to All" when responding. If you have any specific settings or policies in place, those might also affect how replies are handled

    Please note that I have provided above information as per your initial question description.

    I have provided specific official document for pure Office 365 exchange online server environment.

    If you have different server environment such as Azure AD . Exchange On-Premise /  Hybrid server or if I did not understand your concern, please feel free to correct me with more brief information scenario so that I can provide you further information accordingly.

    Initially, I have asked for some information, because I couldn't find some more specific or key information in your case description so that we can understand some more specific scenario for your current situation.

    Your valuable cooperation will be greatly appreciated in the community. Thank you once again for your kind contribution.

    Have a great day.
