I noticed that this parameter ("sourceFolder") is added to the ItemsEvents handlers ItemAdd, ItemChange, ItemRemove.

I was wondering what purpose it served, and what information is in it.

Hello German,

Consider passing true to the recursive parameter of the ADXOutlookItemsEvents.ConnectTo() method. In this case, the class connects to the events of all the folders in the folder hierarchy and you need to know the actual folder generating the event.

Ah. Your team has put together a very interesting framework. After doing some inspecting I see that what you mean by folder you mean the default folders like "Calendar", "Inbox", etc.

In my current project we only process events coming from the Calendar. "sourceFolder" will simplify the logic.

Very nice design.

Nope. I meant "a folder with subfolders". That is, you can connect to the events of the Items collection of a folder and all its subfolders if you set the "recursive" parameter of the ConnectTo() method to true. The sourceFolder parameter of the corresponding event handlers let you identify the folder producing the event in this case.
