Usando o Outlook para Android para gerenciar e-mails pessoais e a agenda
Thanks for reaching out. Which Outlook version are you using right now, the Windows desktop app or Outlook on the web?
Outlook only offers delivery and read receipt options in the Windows desktop app. You open a new email, select Options, then choose Request a Delivery Receipt or Request a Read Receipt. Outlook on the web does not show these options based on Microsoft’s guidance. Let me know your version so I can point you to the exact steps.
