引用共享收件箱，错误：不允许分配给常量

Question

我有一个代码：

1. 转到共享邮箱 (Inquiry@company.com) 下方的特定文件夹（“公司 A 状态报告”）。
2. 搜索未读邮件 + 主题词组：“A 公司状态报告”
3. 接收符合条件的电子邮件，找到最后一封电子邮件，然后检查附件是否存在。
4. 如果存在附件，则下载文件。

该代码以前可以运行，但现在我在此行出现错误：

Set olFolder = oOlns.GetSharedDefaultFolder(olShareName, olFolderInbox) '// Inbox

错误是：

"不允许赋值给常量"

抱歉，还不能发表评论。

错误可能由以下原因引起：

Const olFolderInbox As Integer = 6

如果您将其更改为正常的olFolderInbox = 6，它可能会解决您的问题。

我有类似的 vba，它打开收件箱，然后检查电子邮件详细信息并遍历它们。

我设置了不同的Dim's

Dim myOlApp As New Outlook.Application
Dim filteredItems As Outlook.Items
Dim Ns As Outlook.Namespace
Dim Folder As Outlook.Folder
Dim olSharedName As Outlook.Recipient

在哪里

Set Ns = myOlApp.GetNamespace("MAPI")
Set olSharedName = Ns.CreateRecipient("e'mail@domain.com") 
Set Folder = Ns.GetSharedDefaultFolder(olSharedName, olFolderInbox)

希望我有所帮助。
