Hi Community

I have created a flow that at the end sends an email from a shared mailbox.

The email address is being used from a SP list person or group field using dynamic content so I cant see why this is an issue?

The 'inputs.parameters' of workflow operation 'Send_an_email_from_a_shared_mailbox_(V2)' of type 'OpenApiConnection' is not valid. Error details: The API operation 'SharedMailboxSendEmailV2' is missing required property 'emailMessage/Attachments/0/Name'.

Since you don't show your actual flow, it is hard to say what the issue is. However, based on the error message you posted, you added an attachment to the e-mail and it doesn't have a filename. Please share how you have configured the workflow and especially the action that failed.
