如何在移动电子邮件时唯一标识 Outlook 电子邮件作为 MailItem.EntryID 更改 [英] How to uniquely identify an Outlook email as MailItem.EntryID changes when email is moved

问题描述

我的公司使用一个电子邮件地址供客户发送请求和订单.我们创建了一个 Access 数据库，用于将电子邮件导入表中.该表为每封导入的电子邮件创建自己的唯一标识符，但不应将电子邮件导入两次.系统运行正常，因为我们只关心进入收件箱的电子邮件，除此之外别无他求.

My company uses a single email address for customers to send requests and orders to. we created an Access database that import emails into a table. The table creates it's own unique identifier for each email imported but is not supposed to import an email twice. The system was working as we were only concerned with emails coming into the inbox and didn't need anything more than that.

但是，我们现在需要知道该帐户所在的电子邮件池的流量"、流量"和工作量".进入收件箱的电子邮件被分类，然后移动到一个名为my_tasks"的文件夹和一个子文件夹，该文件夹被命名为经理要处理的四个 CSR 之一.然后处理这封电子邮件，CSR 将其移至另一个名为已完成"的文件夹下的子文件夹.

However we now need to know the "flow", "traffic" and "workload" of the email pool that this account is. The email that comes into the inbox is categorized and then moved to a folder called "my_tasks" and a subfolder the folder named as 1 of the four CSRs to be worked on by a manager. This email is then dealt with and the CSR moves it to a subfolder under another folder called "Completed".

因此电子邮件进入收件箱，移至 my_tasksjoeblow 处理并移至 CompletedCanada.

So email comes into Inbox, gets moved to my_tasksjoeblow is dealt with and gets moved to CompletedCanada.

目前我有代码遍历文件夹并查找每封电子邮件，获取我们想要存储的字段，然后将它们插入表中.所有这些都是通过 VBA 代码在 Access 中完成的.

Currently I have code that iterates through the folders and finds each email, grabs the fields we want to store and then inserts them into the table. All of this is done in Access through VBA code.

有没有办法用单个字段唯一标识一封电子邮件，不管它是否被移动过?

Is there a way to uniquely identify an email with a single field no matter whether it has been moved or not?

我知道我可以做些什么来确保我拥有正确的电子邮件并在我的数据库中获取原始条目.如果没有其他方法，我可以将字段连接在一起形成唯一字段，然后获取数据库表的主键字段值.

I have an idea of what I could do to make sure I have the right email and get the original entry in my database. If there was no other way I could concatenate fields together to form a unique field and then get the database table's primary key field value.

推荐答案

您可以使用 PR_SEARCH_KEY 属性(DASL 名称 http://schemas.microsoft.com/mapi/proptag/0x300B0102) - 当消息移动时它不会改变.它可以通过 MailItem.PropertyAccessor.GetProperty 访问，但遗憾的是您不能在 Items.Find/Restrict 中使用 PT_BINARY 属性.

You can use the PR_SEARCH_KEY property (DASL name http://schemas.microsoft.com/mapi/proptag/0x300B0102) - it does not change when a message is moved. It can be accessed through MailItem.PropertyAccessor.GetProperty, but unfortunately you cannot use PT_BINARY properties in Items.Find/Restrict.

您还可以使用 MailItem.UserProperties 设置自己的命名属性.

You can also set your own named property using MailItem.UserProperties.

更新:

对于 PR_SEARCH_KEY，请参阅 https://msdn.microsoft.com/en-us/library/office/cc815908.aspx.

MaillItem.UserProperties 可以在任何地方使用 - Outlook 对象模型就是 Outlook 对象模型，无论它是从 Outlook 内部使用还是从 Excel 外部使用.请记住，设置用户属性并保存该项目将更改其上次修改日期.

MaillItem.UserProperties can be used from anywhere - Outlook Object Model is Outlook Object Model whether it is used from inside Outlook or externally from Excel. Keep in mind that setting a user property and daving the item will change its last modified date.

如果您想坚持使用 PR_SEARCH_KEY，以便能够对其进行排序，您可能需要查看 Redemption - 它的 RDOFolder.Items.Find/Restrict 方法允许 PT_BINARY 属性在其查询中，例如<代码>http://schemas.microsoft.com/mapi/proptag/0x300B0102"= '89F75D48972B384EB2C50266D1541099'

If you want to stick to PR_SEARCH_KEY, to be be able to sort on it, you might want to look at Redemption - its RDOFolder.Items.Find / Restrict methods allow PT_BINARY properties in its queries, e.g. "http://schemas.microsoft.com/mapi/proptag/0x300B0102" = '89F75D48972B384EB2C50266D1541099'
