How to Access Outlook Shared Mailbox Contact Groups

(0) ShareShare
ReportReport
Posted on by JS-31031540-0
I am trying to access a contact group via a shared mailbox in Outlook, to build a flow to automatically send out emails to all users in the group.

Is this action unable to correctly parse all email addresses within the group contact?


I use the default "Contacts" folder ID, as we do not use any specific folders, but the array returns blank upon testing my flow.
I read you can send HTTP requests for Microsoft Graph but could not determine if that solution fit my issue.

Any advice?

    The "Get contacts (V2)" action often returns a blank array because it's looking for individual people, not Contact Groups, and it usually defaults to your own mailbox instead of the shared one.
    Here is the direct fix:
    Specify the Mailbox: In the action settings, explicitly type the Shared Mailbox email address in the "Mailbox Address" field.
    The Problem with Groups: Even if you point it correctly, this action rarely "unpacks" the members of a Contact Group. It treats the group as one object with no email address.
    The Best Solution: Switch from a "Contact Group" to a Distribution List or M365 Group. This allows you to use the "Get group members" action, which is designed exactly for this and returns a clean list of emails.
    Graph API route: If you must use the current setup, use the "Send an HTTP request" action with this URI:
    GET https://graph.microsoft.com/v1.0/users/SHARED_EMAIL/contactFolders/FOLDER_ID/childFolders (or /contacts).

    No way to do that using Power Automate or Graph. Try to create an Outlook script or an add-in if you definitely need to work with contact groups.
