ews java api - 如何将 permission/classification (public/restricted/internal) 设置为电子邮件

Question

我正在自定义文件夹中起草电子邮件。

EmailMessage msg= new EmailMessage(service);
msg.setSubject("Hello world!");
msg.setBody(MessageBody.getMessageBodyFromText("Draft email using the EWS Java API."));
msg.getToRecipients().add("someone@contoso.com");
// Tried to set extended property but not worked
ExtendedPropertyDefinition headerProperty = new ExtendedPropertyDefinition(
                    DefaultExtendedPropertySet.InternetHeaders,
                    "X-Classification",
                    MapiPropertyType.String);
            msg.setExtendedProperty(headerProperty,"Provision X-header Internet message header");
msg.save(CUSTOM_FOLDER_ID);

我了解到扩展属性对 classification/permission header 会有帮助。参考 link - https://docs.microsoft.com/en-us/exchange/client-developer/exchange-web-services/how-to-provision-x-headers-by-using-ews-in-exchange 但是如何设置 classification/permission ？ X-Classification-Restricted 像这样或任何其他方式？

我不想使用 setImportance / setSensitivity 方法。

手动设置如下

ews 的期望 api 从代码中设置 classification/permission

如何设置权限/分类(public/限制/内部）到 EmailMessage 使用 ews java api?

赞赏工作示例的代码片段。提前致谢

Answer 1

x-iccategory 需要 InternetHeaders 才能将 classification/permission 设置为电子邮件。

x-iccategory with value from [1-4] & supply value as string

以下是具有 classification/permission 类型 x-iccategory

的值

1=高度评价， 2=受限， 3=内部， 4=Public

示例代码片段如下

   EmailMessage msg = new EmailMessage(exchangeService);
                msg.setSubject("Ews api code....");        
                msg.setBody(MessageBody.getMessageBodyFromText("** Email with classification using EWS Java API."));
                msg.setFrom(new EmailAddress("some1@test.com");
                msg.getToRecipients().add("some2@test.com");


            // Define the extended property
            ExtendedPropertyDefinition extPropDef = new ExtendedPropertyDefinition(DefaultExtendedPropertySet.InternetHeaders, "x-iccategory", MapiPropertyType.String);

            // Stamp the extended property with value on a message. 2- Restricted
            msg.setExtendedProperty(extendedPropertyDefinition, "2");

            msg.send();

Classification/permission 不适用于来自 draft/custom 文件夹的电子邮件

注意 - Classification/Permission 会在您触发该电子邮件时出现。电子邮件首先进入传输管道并根据值（Restricted/Public...）应用它
