cannot create a group file or contacts list that works in new outlook. I can create and name the contact list and even place names in the group, but when i try to sent a group email it fails to send to the members of the group.

    Dear @Harold DeLauder,

    Thank you for posting your question in the Microsoft Q&A forum.

    I apologize for any inconvenience you may encounter when using our services/ products. Based on your description:

    This behavior may occur when the New Outlook for Windows does not correctly resolve a Contact List into individual recipients when you send the message.

    In the meantime, kindly try this workaround step:

    • Start a New mail.
    • In To, type/select your Contact List name.
    • Select the “+” (plus) icon next to the list name to expand it into individual addresses.
    • Send again.

    If you do not see the “+” option to expand the Contact List, please try recreating the list in People (New Outlook) and test again:

    People > New Contact > New contact list > Add members > Send an email to the list (and expand with “+” if it’s available).

    I sincerely hope you understand that the initial steps I suggested may not have completely fixed the issue, as there may still be underlying causes that have not yet been identified. I am here to work closely with you, troubleshoot effectively, and explore every possible solution to ensure the best possible outcome.
