Vba Outlook下载附件宏跳过奇数文件

我继承了一段在Outlook 2010中从用户窗体运行的代码。代码应将所选电子邮件中的所有附件保存在公用文件夹中，并保存到用户的C驱动器中

用户向我保证（在过去3年中），他们必须在早上的第一件事“预热宏”。他们说，如果他们选择100封电子邮件，宏将忽略一些附件。但是，如果他们从选择10封电子邮件开始，宏将起作用。然后他们在下一次跑步中选择20，并不断增加

我成功地复制了一次，但只有一次，我不明白为什么

如有任何建议或分享经验，将不胜感激

是的，如果您没有给代码足够的时间来保存附件，这是非常有可能的。最简单的修复方法是在

objAttachments.Item（iLoop）.SaveAsFile strFile

之后添加

DoEvents

另一种方法是在该行之后使用

DIR

，检查文件是否已实际保存

Debug.Print DIR(strFile)

像这样的

Do While Dir(strFile) = ""
    DoEvents
Loop
