One account is ok now (primary), I can send emails from it. Still can’t send emails from other 2. I checked email account settings of two non working accounts and they matched settings of working account

It  makes it confusing when you sign in  using two different usernames .  Plus each  username  is assigned to  an employee  so you probably would have gotten  two different employees responding to you and that right there  takes away time from another customer  but it's also  confusing the issue that you're trying  to have solved.  And I'm glad that we were able to get it solved .  I enjoyed working with you !
