c# - Outlook COMException

system.runtime.interopservices.comexception..服务器管理员限制了可以同时打开的项目数…
在microsoft.office.interop.outlook.\u appointmentitem.get\u userproperties（）

        var calendar = outlookApplication.GetNamespace("MAPI").GetDefaultFolder(OlDefaultFolders.olFolderCalendar);

        if (calendar == null || calendar.Items == null)
        {
            return null;
        }

        var calendarItems = calendar.Items;

        if (calendarItems != null && calendarItems.Count > 0)
        {
            // Dont convert to LINQ or foreach please -> may cause Outlook memory leaks.
            for (int counter = 1; counter <= calendarItems.Count; counter++)
            {
                var appointment = calendarItems[counter] as AppointmentItem;

                if (appointment != null)
                {
                    var userProperty = appointment.UserProperties.Find("myInformation");

                    if (userProperty != null && userProperty.Value == myValue)
                    {
                        return appointment ;
                    }
                }
            }
        }

可能是它的appointment.userproperties.find（“myinformation”）导致了ComException？

最佳答案

完成outlook邮件项目后，将其关闭，然后将其释放

For Each item As Outlook.MailItem In oFolder.Items
  '<process item code>

  'Close the item
    'SaveMode Values
    'olDiscard  = 1
    'olPromptForSave = 2
    'olSave = 0
  item.Close(1)

  'Release item
  Marshal.ReleaseComObject(item)
Next
