示例 2：导入邮件

以下示例演示如何导入消息。 有关详细信息，请参阅 使用 Microsoft Graph 将消息导入Microsoft Teams 聊天和频道。

注意：此方案需要权限范围 Teamwork.Migrate.All 。 目标聊天必须处于迁移模式。

重要

createdDateTime 在目标聊天中必须唯一到毫秒。 如果存在具有相同 createdDateTime 的消息，则请求失败并出现 409 Conflict。 调整 createdDateTime 并重试。 有关详细信息，请参阅 使用 Microsoft Graph 将消息导入Microsoft Teams 聊天和频道。
