mail.sendemailv3 failed: the server returned an http error with code 400

Just wondering if others are seeing this error (when sending an email from a Power App) - we have multiple users reporting that they started seeing this error is appearing intermittently this week:

 

mail.sendemailv3 failed: the server returned an http error with code 400

 

There have been no changes to the App, so I'm guessing this may be a service error and would like to confirm/reject that possibility.

    Hi @PaulD1 ,

    For this kind of issue, I would suggest you quickly contact with Microsoft post-sales support team. You will get a most effective reply from there. The support engineers there have more resources(latest information about new updates or server issue), maybe they already had handled these kind of issues recently.

    Best regards,

    Thanks @v-albai-msft 

    Looks like it wasn't a widespread issue and seems to have cleared up within a few hours (no more reports of issues).
