Send email from shared mailbox - "Resource could not be discovered"

[Ftejani]

Dear

I am in the process of creating a flow to send an email from a shared mailbox and receive the following error when running:
Status code = 404
{
"status": 404,
"message": "Resource could not be discovered.\r\nclientRequestId: b1f97f82-706e-4804-a510-6e4088215bc9\r\nserviceRequestId: 159481e6-474a-4f1b-8866-2725dd0dc8ad",
"source": "office365-eus.azconn-eus-01.p.azurewebsites.net"
}

My account has fulll access to the shared mailbox and it is being used as account for the connector.

I would really appreciate any kind of help or pointers in how this can be solved 🙂

Thanks
Regards
Farzad

Hi @Ftejani ,

Flows fail if a setting in an action of the flow doesn't function as expected. In this case, the error message contains Bad request or Not found, or an error code of 400 or 404 appears.

Please share the details of the Flow configuration so that we can analyze the issue.

In addition, you should pay attention to the following two points when configuring the action related to Shared mailbox:

• The account that configures the connection (in this case, your account) needs to be a member of the Shared mailbox.
• You need to remove semicolon at the end of the Mailbox Address.

Please take a try again.

Best Regards,
