Question

我使用Office 365 REST API来获取邮件附件。我可以正常获取文件附件，但如果附件的类型为"#Microsoft.OutlookServices.ItemAttachment"。我得到这个ItemAttachment的ID，然后使用此请求获取文件附件：
https://outlook.office.com/api/v1.0/me/messages/MESSAGE_ID/attachments/FILE_ITEM_ID?$expand=Microsoft.OutlookServices.ItemAttachment/Item

响应返回具有新属性＆＃34; Item＆＃34;，包含＆＃34; #Microsoft.OutlookServices.Message＆＃34; HasAttachments = false。但是尝试使用Web Outlook版本，我可以得到这个Item Attachment（在这种情况下是一个.eml文件，exec它将打开一个新的邮件表单）。这是一个例子：

＆＃13;

那么，如何使用Office 365 REST API获取此.eml文件？有人可以帮助我吗？谢谢！

Answer 1

Office 365 apis不会将您的商品附件作为* .eml文件提供。如果您需要将 ItemAttachment 作为* .eml文件，则必须自己构建它。以下是步骤：您可以访问此邮件的所有信息（请参阅新的项条目），以便您可以创建 MailMessage 实例，然后调用一个提议的技术这里将 MailMessage 保存到* .eml文件How to save MailMessage object to disk as *.eml or *.msg file

注意：您没有提到用于请求Office365 apis的技术堆栈，我认为它是C＃。
