Invoke RDOItem.Item throws Exception 0x8004010B RRS feed

  • Question

  • Hi,

    I am using Redemption to iterate the hiddenitems.

    On one computer I receive the following exception invoking rdoItems.Item(counter):

    System.Reflection.TargetInvocationException: Ein Aufrufziel hat einen Ausnahmefehler verursacht. ---> System.Runtime.InteropServices.COMException (0x8004010B): Error in IMAPITable.QueryRows: MAPI_E_BUSY

    The code works normaly without any problem.

    Can anybody give me a tip what I can do?

  • Hi Christian,

    Redemption is a commercial component. That's why I'd recommend contacting the Redemption developer directly at .

    As far as I understand the cause of the issue is the QueryRows method. MSDN provides the following description:

    If QueryRows returns MAPI_E_BUSY, retry the call to QueryRows when the asynchronous operation is complete.

    The MAPI_E_BUSY error means the following: Another operation is in progress that prevents the row retrieval operation from starting. Either the operation in progress should be allowed to complete or it should be stopped.
