问题描述
我们开发了outlook addin，我们将它部署在outlook 2010 sp2上，并且有最新的补丁。
we have developed outlook addin and we deployed it on outlook 2010 sp2 and is having latest patch.
现在在几台安装了插件的机器上，同时试图获得outlook预约项目的rceipients属性。我收到此错误
Now on few machines where addin is installed , whilst trying to get rceipients property of outlook appointment item. i get this error
无法将"System .__ ComObject"类型的COM对象强制转换为接口类型"Microsoft.Office.Interop.Outlook._AppointmentItem"。此操作失败，因为由于以下错误，对IID为"{00063033-0000-0000-C000-000000000046}"
的接口的COM组件的QueryInterface调用失败：库未注册。 （HRESULT的例外情况：0x8002801D（TYPE_E_LIBNOTREGISTERED））
dim AppItemas outlook.appintmentitem
dim AppItemas outlook.appintmentitem
Dim Recipients As Outlook.Recipients = Nothing
Dim Recipients As Outlook.Recipients = Nothing
收件人= AppItem.Recipients（假设apppitem已被初始化） - 受影响的计算机在此处收到错误
Recipients = AppItem.Recipients (assume apppitem has been initalised) --effected machines are getting error here
当我尝试访问一个MAPI文件夹时也会出现类似的错误，该文件夹实际上是一个保存在.net集合对象中的celndaritem
I also get similar error when try to access the a MAPIfolder which is actually a celndaritem saved in .net collection object
Dim CalendarFolderItems As Outlook.Items = Nothing
Dim CalendarFolderItems As Outlook.Items = Nothing
索引= 1到CalendarCollection.Count
                 记录（"循环的setlocation"+ index.ToString（））
                 如果（CalendarCollection（index）.EmailAddress = email）则为
                     记录（"setlocation email"+ + email）
                      CalendarFolderItems = CalendarCollection（index）.FolderItems - 受影响的计算机在此处收到错误
For index = 1 To CalendarCollection.Count
Log("setlocation for loop " + index.ToString())
If (CalendarCollection(index).EmailAddress = email) Then
Log("setlocation email " + email)
CalendarFolderItems = CalendarCollection(index).FolderItems -- effected machines are getting error here
                结束如果
End if
下一步
现在，我们已经尝试修复有效机器的展望但是它没有解决问题
Now, we already tried repairing outlook on effcted machine but it did not resolve issue
不确定但可能是由于注册表中的一些冲突？
Not sure but can it be due to some conflict in registry?
谢谢
