Enviar mensagens com conteúdo MIME

  • Artigo

Muitos clientes de email podem enviar mensagens pelo Exchange em um formato de mensagem MIME e se comunicar em várias plataformas de email.

A API de email do Outlook oferece suporte às seguintes ações em mensagens com conteúdo MIME:

  • Enviar mensagens.
  • Enviar mensagens para responder ou responder a todos.
  • Encaminhar mensagens.
  • Criar mensagens de rascunho.
  • Anexe assinaturas S/MIME a mensagens.
  • Criptografe o conteúdo da mensagem usando S/MIME.

Importante

  • O S/MIME fornece dois recursos principais: assinaturas digitais para verificar o conteúdo do remetente e do email, e criptografia de mensagens para impedir que terceiros vejam o conteúdo do email.
  • Adicione assinaturas digitais S/MIME e conteúdo criptografado a emails somente no formato de mensagem MIME.

Para saber mais sobre o formato MIME, consulte como obter conteúdo MIME de uma mensagem.

Especificar o corpo da mensagem MIME e o cabeçalho de solicitação

Você pode criar uma mensagem no formato JSON ou MIME. Especifique o formato pretendido no cabeçalho da solicitação:

  • Content-Type: application/json para usar o formato JSON no corpo da solicitação.
  • Content-Type: text/plain para usar o formato MIME no corpo da solicitação.

Ao especificar o corpo no formato MIME, forneça os cabeçalhos de mensagem de Internet e o conteúdo MIME aplicáveis e codifique-os no formato base64 no corpo da solicitação. O Microsoft Graph não dá suporte à edição nem à atualização de propriedades MIME individualmente.

Exemplo

Veja a seguir um exemplo de conteúdo MIME com títulos de mensagens da Internet (antes da codificação):
