Question

我有以下用例。

客户希望转发多个联系人的特定现有电子邮件。因此，每个联系人都有包含附件的电子邮件。

所以我需要提取相关的联系人，它们是包含附件的电子邮件，然后将其发送到另一个电子邮件地址。

我可以检索相关的联系人，但是现在我不知道如何检索电子邮件，附件并将它们链接在一起，以便可以发送它们。

有人可以给我一些建议吗？这将是极好的，并受到高度赞赏。

Answer 1

以下是可以执行此操作的工作流的一个示例。附件的实体称为activitymimeattachment。此代码从电子邮件中提取附件并将其转换为便笺。在您的情况下，您应该使用“ attachmentid”，“ filename”，“ mimetype”创建新电子邮件，我认为这已经足够了。祝你好运！
