Enviar, receber e organizar e-mails no Outlook.com
Hi Maria Claudia, thanks for the details. Are you able to check if the drafts appear when using a different browser or device?
Outlook.com creating drafts repeatedly usually happens because of a corrupted item in your mailbox. Microsoft supports fixing this by contacting Support and requesting a mailbox repair and dumpster reset. You can check this link: https://support.microsoft.com/en-us
