excel - 将电子邮件详细信息从 Outlook 导出到 Excel

Question

我有一个代码(我从 How do you extract email addresses from the 'To' field in outlook? 和另一个消失的来源中复制并稍微编辑了它)目前正在运行以提取日期、姓名和电子邮件地址(发件人、收件人、抄送)中的每封电子邮件一个特定的邮件文件夹。然而，在交叉引用从 Outlook 手动导出的电子邮件列表(通过导入和导出向导)后，我意识到大约有 30 封电子邮件在 VBA 导出表中有错误。对于包含各自电子邮件信息的每一行，“发件人”、“收件人”和“抄送”中的名称均为空白，而相应的电子邮件列只是成功提取的前一封电子邮件的副本。到目前为止，根据我的观察，这些电子邮件之间的相似之处在于它们都是针对 Microsoft 团队 session 的(例如，邀请参加团队 session )。下图描述了错误:

此外，一个人有两个电子邮件地址(每个地址都有不同的域)。但是，只有一个邮箱地址成功导出了对应的邮箱；包含其他电子邮件地址的电子邮件无法导出该特定电子邮件地址，即使他们的名字仍然存在。同样，错误是这样的:

请帮助我识别并在可能的情况下纠正上述问题，因为我在编码方面几乎没有经验。提前致谢。代码如下-

错误处理可能很乏味，这就是为什么经常看到一揽子 On Error Resume Next 的原因。这会隐藏错误，因此结果不可信。对于没有经验的人来说，“代码运行”是莫名其妙的。

可以说 On Error GoTo ExitFunction 更好，因为它没有给出任何结果，因此您会意识到存在问题。

在删除了 On Error Resume Next 和 On Error GoTo ExitFunction 后，您可以在看到需要错误处理的位置后构建自己的错误处理逻辑。

按您认为合适的方式进行调整。
