SMTP settings doesn't work well with Exchange Online

Hi, thanks for replying. Before posting here I’ve already tried my credentials with:

  • Local mail client with IMAP (for sending) and SMTP configured => worked
  • A WordPress instance with Remote SMTP plugin with SMTP configured => worked

I also tried to use mycorpemail along without the domain name in User field but it still didn’t work.

I’d like to know if anyone else here mange to make Zammad work with Exchange Online SMTP.

Thanks!
