I have created a powerapp and on clicking a button, I want to send emails. I used the Outlook connector to create the connection and used Office365Outlook.SendEmailV2 function. defined all parameters well. 

But this fails to execute and the said error is thrown. Please help me with this.

Hi @vineet2 

Looks the user does not have permission to send an email. Please assign or ask them to assign permission to this user.

This applies to sending emails on behalf of another user as well.

Is this happening for all users or specific users?

Please work with the IT admin to set up permission in Office 365.

Thanks,
