Send email from M365 Group's mailbox

(0) ShareShare
ReportReport
Posted on by

I have a flow that creates tasks in a Planner from data submitted in an MS Form. Based on a condition, I would like to send an email to the email supplied in the submitted form which will include followup information. I saved the document in my OneDrive and shared with everyone and then get the document from there to add as an attachment in the email. The one piece I am missing is to send the email from the M365 groups mail box and not mine or a service account as I want the email conversations to continue via that mail account. Is that possible? I tried using send email (v3) but it asks me to sign up for a service and I am not sure what that means.

    Hi @AnnetteM ,

     

    Does the M365 Group's mailbox means "Shared Mailbox"? https://docs.microsoft.com/en-us/microsoft-365/admin/email/create-a-shared-mailbox?view=o365-worldwide 

     

    If it is "Shared Mailbox" you need "Full Access" permission for the "Shared Mailbox" to send/interact/read emails from your Outlook application side.

     

    Action Plan

    ===========

    1. Contact your Exchange admin

    2. Ask to grant "Full Access" permission of the Shared Mailbox to your account: https://docs.microsoft.com/en-us/exchange/collaboration-exo/shared-mailboxes#which-permissions-should-you-use 

    3. Open and use a shared mailbox in Outlook: https://support.microsoft.com/en-us/office/open-and-use-a-shared-mailbox-in-outlook-d94a8e9e-21f1-4240-808b-de9c9c088afd?ui=en-US&rs=en-AU&ad=AU

     

    Hope this helps. Thanks!

     

    Best regards,

    Jisung Han

    The mailbox is inherited (as the calendar) from the creation of an M365 group which is necessary to create a Planner. I am the owner of the group. I don't believe it may be the same as a traditional "shared mailbox" in exchange as the M365 group is part of the cloud.

    @AnnetteM 

    Try using the Send an email from a shared mailbox action instead.

    I have also tried that using the M365 group's email address in the "Original Mailbox Address" field and get this message:

    I also found that there is an Office 365 Groups Mail Connector (https://flow.microsoft.com/en-us/blog/use-our-new-office-365-groups-mail-connector/) which I think would suffice in this instance, however it is not available to GCC.
    Any other ideas?

    Hi @AnnetteM , just use the "Send an email (V2)" action. Populate the field "From (Send as)" and place there the address of your group.

    As I noted above, even though I am the owner of an M365 group, I still get the message that I don't have rights to send on behalf of. M365 groups must have some nuances to them.

    Hi @AnnetteM,

     

    did you assign yourself the "send as" right also? (Edit Microsoft 365 Group > Group Delegation) 

  • AnnetteM Profile Picture

    Ah, that was the piece I was missing. So to summarize:

    • I added a service account as a "send as" delegate on the M365 group
    • Used "Send an email (V2)" action with the M365 groups email in the "From(Send as)" field
    • Used the service account as the connection for the "Send an email (V2)"

    Thank you!
