The MailTip shows 200+ members in a DL but the DL actually have 4 members. Could anyone know how to fix?

    Hi @Austin Sundar

    What's the version of your Exchange server?
    Is it only affecting this particular distribution list? Have you removed group members from this DL recently?

    Please have a check in both Outlook and OWA and see if there is any difference.
    It's also suggested to run the command below to verify the members included:

    Get-DistributionGroupMember -Identity <DLName>
