尝试从Outlook归档电子邮件文件

Question

我们正在尝试削减Outlook PSTs的大小，在项目完成后，不再将相关的电子邮件拉出到各种项目文件夹中。因此，在实现副本之后，您只需退出Outlook几乎无法运行，并且不会继承其任何元数据，我一直在寻找其他解决方案。并找到了一些部分VBA脚本来做它，我已经拼凑在一起并在这里改变以尝试获得我想要的东西。

例程从Outlook中读取选择，并根据需要将电子邮件保存到提供的时间戳和发送者或接收者的位置。分类到子文件夹。那部分似乎运作得很好。但在我的测试中，我在238封电子邮件的outlook文件夹上运行，我的测试日志有233个条目，但只输出了231个文件。有什么想法吗？

可能是因为文件夹太大了？这样我可能需要在较小的部分中进行。或者超越自己，这样我需要在某处添加延迟？

Answer 1

感谢上面评论中的0m3r和niton帮助我弄明白。那里有一些日历笔记，当然不是电子邮件，因此必须将其删除，并且一些电子邮件与相同的发件人，时间和主题一起到达，因此脚本会覆盖它们。

在此之后我遇到了一些问题，让Outlook在其他机器上运行以允许宏运行。所以我回过头来重写为C＃中的VSTO插件。只有我更改的功能是让RemoveSpecials检查除时间之外的所有内容，并添加路径长度检查，因此事情不会生成超过260个字符。哪会导致事情停止。

这是我搬到c＃
