COMException:客户端操作失败 Outlook [英] COMException: A client operation failed Outlook

问题描述

在我的应用程序中，我存储了不同的文件夹 EntryID(电子邮件、联系人...)以便以后选择它们.问题是，有时我会收到 COMException:

in my Application I store different Folders EntryIDs (Emails, Contacts...) in order to select them at a later point. The problem is, sometimes I get a COMException:

客户端操作失败.(在Microsoft.Office.Interop.Outlook.NameSpaceClass.GetFolderFromID(StringEntryIDFolder, Object EntryIDStore))

更新:我在同一个操作中又收到一条错误信息(没有修改代码)

Update: I got another error message at the same operation (without modifying the code)

消息传递接口返回了一个未知错误.如果问题仍然存在，请重新启动 Outlook

我的代码如下:

       outlookApp.Session.GetFolderFromID(searchFolder);

OutlookApp 是这样定义和声明的:

OutlookApp is defined and declared that way:

 private ApplicationClass outlookApp;
try
        {
            outlookApp = new Microsoft.Office.Interop.Outlook.ApplicationClass();
        }
        catch (System.Exception)
        {
            try
            {
                outlookApp = Activator.CreateInstance(Type.GetTypeFromProgID("Outlook.Application")) as Microsoft.Office.Interop.Outlook.ApplicationClass;
            }
            catch (System.Exception)
            {
                outlookApp = System.Runtime.InteropServices.Marshal.GetActiveObject("Outlook.Application") as Microsoft.Office.Interop.Outlook.ApplicationClass;

            }
        }

我的建议是，这以某种方式连接到共享文件夹，但我无法定期重现该错误.Outlook 处于缓存模式.Exchange 在日历方面抛出了很多同步错误，但我没有在处理它们.我无法在带有用户邮箱的测试虚拟机上重现该错误.我尝试使用办公室的内部工具进行修复(发现错误)，但这也没有解决任何问题.

My suggestion is, that this is somehow connected to shared folders, but I am not able to reproduce the error on a regular basis. The Outlook is in Cache Mode. Exchange is throwing a lot of Sync Errors with Calendars, but I'm not working on them. I cannot reproduce the error on a test vm with the users mailbox. I tried repairing with the internal tool from office (it found errors), but this did not fix anything either.

推荐答案

如果您在网络环境中工作，则会出现错误.这是不可避免的.您的代码必须准备好处理此类错误.

If you are working in a networked environment, you will have errors. This is unavoidable. Your code must be prepared to handle errors like that.
