Dear ADX-Team,

to use the ItemsEventClass we have to hook the event class like this: 

OutlookItemsEvent.ConnectTo(ADXOlDefaultFolders.olFolderInbox, true);


Am I right, the event class will not work for the inbox sub folder?

Thanks and regards,
Birger

Hello Birger,

Yes, you are right. But the following call of the ConnectTo method will handle sub-folders: 

OutlookItemsEvent.ConnectTo(ADXOlDefaultFolders.olFolderInbox, true, true);

It's confusing. Sometimes the ItemAdd event is fired when d'n'd a mail to another folder on different exchange server, sometimes the BeforeItemMove and ItemChanged event is fired. Why is not always the ItemAdd event fired?

Thanks an regards,
Birger

Hello Birger,

Could you please send me your project (or even better a small demo project with the same behavior) for testing? I will try to find out the cause.

Hi Dmitry,

I will try to explain it first.
When I hook the event class like this: 

        
private void AddinModule_AddinStartupComplete(object sender, EventArgs e)
        {
            // items event class
            OutlookItemsEvent = new OutlookItemsEventsClass(this);
            OutlookItemsEvent.ConnectTo(ADXOlDefaultFolders.olFolderInbox, true, true);
        }


Only one of three mailboxes will fire the ItemAdd event. Do I have to hook the event class in a different way, that all mail accounts will fire the event when I drop mails from one incoming mail folder to another?

Thanks and regards,
Birger

Hello Birger,

The ConnectTo() method connects to events of the default Outlook store only. To handle all stores you need to loop through the https://msdn.microsoft.com/en-us/vba/outlook-vba/articles/stores-object-outlook collection, get Inbox folders by using the https://msdn.microsoft.com/VBA/Outlook-VBA/articles/store-getdefaultfolder-method-outlook method, create a new OutlookItemsEvent class and call the ConnectTo(folder, true, true) method.

Hi Dmitry,

thanks a lot.
I solved it like this: 


  private void AddinModule_AddinStartupComplete(object sender, EventArgs e)
        {
            // items event class
            Outlook.NameSpace olNs = null;
            Outlook.Stores olStores = null;
            try
            {
                olNs = AddinModule.CurrentInstance.OutlookApp.Session;
                olStores = olNs.Stores;
                for (int i = 1; i < olStores.Count; i++)
                {
                    Outlook.Store olStore = olStores[i];
                    if (olStore != null)
                    {
                        Outlook.MAPIFolder olFolder = olStore.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderInbox);
                        if (olFolder != null)
                        {
                            var olItemEvents = new OutlookItemsEventsClass(this);
                            olItemEvents.ConnectTo(olFolder, true, true);
                            if (OutlookItemsEventList == null) OutlookItemsEventList = new List<OutlookItemsEventsClass>();
                            OutlookItemsEventList.Add(olItemEvents);
                            Marshal.ReleaseComObject(olFolder);
                        }
                        Marshal.ReleaseComObject(olStore);
                    }
                }
            }
            catch (Exception exception)
            {
                log.Warn(exception, "Hook Outlook Event Item Class Exception");
            }
            finally
            {
                if (olStores != null) Marshal.ReleaseComObject(olStores);
                if (olNs != null) Marshal.ReleaseComObject(olNs);
            }
        }


and 




  private void adxOutlookEvents_Quit(object sender, EventArgs e)
        {
            foreach (var olItemsEventClass in OutlookItemsEventList)
            {
                if (olItemsEventClass != null)
                {
                    olItemsEventClass.RemoveConnection();
                    olItemsEventClass.Dispose();
                }
            }
}
