Acesso negado quando você envia um email para um grupo do SharePoint

Sintomas

Os fluxos de trabalho do SharePoint 2013 que tentam enviar um email para um grupo do SharePoint podem falhar com um erro de Acesso Negado se a associação do grupo do SharePoint não estiver definida como Todos.

Motivo

Esse problema ocorre quando o usuário que inicia o fluxo de trabalho não faz parte do grupo do SharePoint. As seguintes entradas são registradas ULS e na página Status do fluxo de trabalho:

Resolução

Existem algumas soluções para esse problema.

• Permita que todos vejam os membros do grupo do SharePoint.
• Remova o grupo do SharePoint da linha Para ou CC do email.
• Adicione explicitamente os usuários à linha Para ou CC se a visibilidade da associação não puder ser alterada para o grupo do SharePoint.
