使用 C# 将 .pst 导入 mysql 时，电子邮件地址显示不正确

Question

我正在使用下面的代码将名为 working 的 outlook 安装的 .pst 文件导出到本地 MySQL 数据库，大部分代码工作正常，但有些 "Sender_Email and "Received_Email" 以 EX 格式显示，如下所示

/o=ExchangeLabs/ou=Exchange 管理组 (FYDIBOPDLT)/cn=Recipients/cn=ed403ae50a4581-a.john

这让我发疯！电子邮件地址应该是 a.john@domain.com 而不是这种笨拙的格式，其他电子邮件在 @domain 等中看起来很好，只是其中一些具有这种笨拙的格式 - 有谁知道我需要编辑什么才能制作这段代码工作正常吗？我在下面包含了所有代码，因为我是一个初学者，而且这段代码不是我自己完整编写的，所以我非常感谢你能给我的任何建议。

        // Remove PST file from Default Profile
        //outlookNs.RemoveStore(rootFolder);
        return mailItems;
    }
}

}

Answer 1

这是一个完全有效的 EX 类型地址（相对于 SMTP）。您可以使用 MailItem.SenderEmailType 属性检查发件人电子邮件地址类型。如果是SMTP，就用MailItem.SenderEmailAddress。如果不是，请使用 MailItem.Sender.GetExchangeUser.PrimarySmtpAddress 属性（准备好处理错误 and/or 空值）。 GetExchangeUser 仅当原始 Exchange 用户在当前 Outlook 配置文件中托管有问题的 GAL 用户时才有效。如果您的配置文件中只有 PST 文件，它将不起作用。可能 PidTagSenderSmtpAddress_W MAPI 属性（DASL 名称 http://schemas.microsoft.com/mapi/proptag/0x5D01001F）在邮件中可用 - 您可以使用 MailItem.PropertyAccessor.GetProperty 访问它 - 查看带有 [=20= 的邮件]（我是它的作者 - 点击 IMessage 按钮）检查属性是否确实存在
