How to refresh reading pane content in Outlook 2010

Question

We use redemption tools to populate stub-mails with real content. After calling RDOMail.Import(...) on the selected item, we close and reopen the preview (reading) pane in outlook using

m_Explorer.ShowPane(MSOutlook.OlPane.olPreview, false);
m_Explorer.ShowPane(MSOutlook.OlPane.olPreview, true);

This method works well in Outlook 2007.

But in Outlook 2010 programmatical refresh attempts (Close/Open Reading pane, Deselect/Select the updated item) do not work at all. Outlook 2010 still shows the old version.

Does anyone have a hint or a possible solution?

Many thanks in advance.

Answer 1

Finally, we solved it!

The solution is to

1) Remove the item to update context.RemoveItem(TargetData.EntryID); (We are using some abstractions over RDOMessage, MailItem, RDOFolder and MAPIFolder. But I think, the principle behind is quiet clear.

2) Add the new item (WithComCleanup is from VSTOContrib project)

using (var msg = RDOSession.Resource.GetMessageFromMsgFile(pathToMSG)
                                                     .WithComCleanup())
{ 
     msg.Resource.Move(context.RDOFolder);
     msg.Resource.Save();
}

3) Attach an ItemAdd handler to RDOFolder or MAPIFolder, note that the items collection has to be declared on class level! Why ItemAdd? Because neither RDOMail.OnModified nor RDOMail.OnMoved provided a valid EntryID required for MailItem retrieval. We write custom UserAttributes on fetching, and read them in ItemAdd...

 //...
 m_OwnItems = m_Folder.Items
 m_OwnItems.ItemAdd += new MSOutlook.ItemsEvents_ItemAddEventHandler(Items_ItemAdd);
 //...

 void Items_ItemAdd(object Item)
 {
     //Outlook 2010: Version 14, only Outlook 2010 supports `ClearSelection` and `AddToSelection`
     if (Item is MSOutlook.MailItem && ApplicationController.Instance.ApplicationVersion.Major >= 14)
     {
         var mail = Item as MSOutlook.MailItem;

         //Check that the added item is the one you added with GetMessageFromMsgFile
         //...

         if (m_Explorer.IsItemSelectableInView(mail))
         {
             m_Explorer.ClearSelection();
             m_Explorer.AddToSelection(mail);
         }
     }    
 }                        

4) It's done! This behavior of Outlook 2010 annoyed us for the whole development time...
