Hi, I'm having an issue using the from field in flow. I get a "You are not authorized to send mail on behalf of the specified sending account." Despite me having the Send as Permission set for that account. If I use the from field in outlook I can successfully send an email with those credentials from my account, but my test flow keeps failing on the same input.

 

I checked that the permissions are correctly granted

    Hi Steve_sear

     

    Usually we have to wait a few minutes until the permissions were replicated, after to give the "Send as" permission, did you wait some minutes?

     

    Thanks.

    Javier.
