'Unauthorized' error when trying to send email notification

[JRG_Jeff]

I'm tryin setup a very simple flow using a template that triggers on a new form submission.  The form in question has just one entry field.  However, I get an 'unauthorized' message when the flow gets to the send email notification section.

The flow connector shows no problems.

Any help is greatly appreciated.

I've already read other posts about this error, but none of them seem to apply.  There is no blocked IP address from the source of the email, and there are no attachments involved in the email.

Hey @JRG_Jeff 

I had a similar problem in the past and then I got to know that Microsoft recommends using the Office 365 Send Mail connector instead.  See: https://docs.microsoft.com/en-us/connectors/sendmail/

Hi CFernandes,

Thanks for the response, but that's the connector I'm already using. I've removed the connect, and I've removed the step; however, the problem still remains with this most recent connector.

I ended up changing it to the "Send an email (V2)" action, and it worked perfectly.  There must be a problem with V3.

THANK YOU! for posting this.  I had a similar experience.  Everything was set up right, but it wouldn't send the email.  V3 was the culprit and switching to V2 fixed it all.  I couldn't find that solution anywhere else.
