VBA展望"No active explorer found"
VBA Outlook "No active explorer found"
我遇到了 Outlook 自动化问题，
为简单起见，我将首先向您展示我的代码的较短版本：
Sub test()
Dim GetOutlookApp As Object
Set GetOutlookApp = CreateObject("Outlook.Application")
End Sub
首先，我确实想保留后期绑定解决方案。
此子在任务栏（小图标）中启动 Outlook。当我双击它时，会弹出一条消息："No active explorer object found"（window 的标题："Error"）。然后，当我单击“确定”时，Outlook 收件箱 window 打开。
我的脚本是为最终用户准备的，所以我不希望出现这条消息，即使用户只需点击确定（主子的其余部分没有任何问题）。
我必须解决这个问题才能使用 outlook 发送电子邮件并确保电子邮件不在发件箱文件夹中。
我正在寻找一种打开 Outlook 的方法，没有此消息，使用后期绑定。
以下是发送电子邮件前打开 Outlook 的完整代码（来源：ron de bruin）。除了 outlook 消息外，它工作得很好。此行弹出消息：
obj.Session.GetDefaultFolder(olFolderInbox).Display
我尝试了 AppActivate 和其他东西，但没有成功，而且在 google 上找不到任何关于它的信息！

使用资源管理器 class（不是文件夹）的 Add method of the Explorers class to create a new instance of the explorer window. Then you need to call the Display 方法。
Sub DisplayDrafts()
Dim myExplorers As Outlook.Explorers
Dim myOlExpl As Outlook.Explorer
Dim myFolder As Outlook.Folder
Set myExplorers = Application.Explorers
Set myFolder = Application.GetNamespace("MAPI").GetDefaultFolder(olFolderInbox)
Set myOlExpl = myExplorers.Add(myFolder, olFolderDisplayNoNavigation)
myOlExpl.Display
End Sub
This sub launch Outlook in the taskbar (small icon). When I double click on it, a message pops up: "No active explorer object found" (title of the window: "Error"). Then the Outlook Inbox window opens when I click on OK.
通常您不应在任务栏中看到任何图标。确保为 OS 和 Outlook 安装了所有最新的更新和服务包。在自动化 Outlook 之前还要检查 运行 个进程的列表 - 确保目前没有 Outlook 实例 运行。
