Error when using When a new email arrives in a shared mailbox (V2)

(0) ShareShare
ReportReport
Posted on by 18

Hi all. I am trying to use the "When a new email arrives in a shared mailbox (V2)" trigger in Power Automate. I am able to enter the name of the shared mailbox in the "Original Mailbox Address" field in the trigger - it pops up with name of the mailbox as I'm typing it and I select it to fill it in so it definitely can see it. However, when I go to select the value for the "Folder" field in the trigger I get an error message that says "The dynamic invocation request failed with error: { "status": 404, "message": "Resource could not be discovered.\r\nclientRequestId: 652fbbad-4c0d-4d5a-bb44-c360e575661b\r\nserviceRequestId: bbfbe55d-ac0d-468f-8bc8-0b95db32b8fe", "error": { "message": "Resource could not be discovered.", "code": "ResourceNotFound", "originalMessage": "Resource could not be discovered." }, "source": "...omitted for privacy reasons***}."

 

Anyone else run into this error? I saw in another post that someone suggested removing the semi-colon from the end of the email address. I tried that but still go the same error.

    It looks like you have insufficient rights. Can you open this shared mailbox from Outlook?

    @VictorIvanidze yes, I can open the mailbox from Outlook and send and receive email. It also auto-populates the name of the mailbox as I start typing it in Power Automate.

    For anyone else that might come across this post in the future, I thought I'd post the solution (to the specific problem I had at least.) It turns out that in my organization, shared mailboxes are, by default, only on-premises, not in the cloud. So, while I could access the mailbox, and Power Automate could "see" it - it needed to be in the cloud in order to actually execute a flow against it. Once the shared mailbox was migrated to the cloud it worked fine.
