Capturing new members of distribution list in Outlook invite

I have a quarterly invite that gets sent to 3 distribution lists. These lists get updated at the start of every month. I understand it is not possible for the distribution lists to automatically send the invites to new members every month, so as a workaround, my idea was to re-add the distributions lists to the invite each time we update it, in order to capture the new members. I created a test group to run the scenario, and it worked (even though it means other attendees receive a notification).

However - I tried this method with the real distribution groups, and have found that new members are not receiving the meeting invite. I have confirmed the new members appear in the group, but they still do not receive it. Is there any advice to make sure this invite can be sent to new members, without having to individually add them to the invite line?

    Hi Carol,

    Regarding your concern, the current article Send a message or a meeting invite to a contact group in Outlook | Microsoft Support does not document removing and re-adding the same distribution list to an existing recurring meeting as a reliable method for inviting newly added members.

    However, since this worked with your test group but not the production groups, I suggest doing these steps to determine whether this is related to the existing meeting or to mail flow:

    • Send a new test meeting to one affected production distribution list and check whether the newly added members receive it
    • If the new members still do not receive it, run an Exchange Online message trace and review the group for sender restrictions, moderation, nested membership, or dynamic membership refresh delays

    If there is anything else I can help with, feel free to reach out again.
