EWS Api 2.0 not returning ID of copied Appointment
<p>I'm having a problem with "Copy" method of "Item":
As explained in documentation (<a href="https://msdn.microsoft.com/en-us/library/dd634844(v=exchg.80).aspx" rel="nofollow">here</a>) that method should return the copied item (and the relative fresh UniqueId), but I can only get a null return object.</p>

<pre><code>Dim obj = existingItem.Copy(folderId) 'obj is null
</code></pre>

<p>I've also tried:</p>

<pre><code>Dim test = service.CopyItems(myListOfItemIds, folderId)
</code></pre>

<p>This is returning something, but still not copied item UniqueId in it...</p>

<p>Does it exists a workaround for this problem? Am I missing something?
Thanks for any help.</p>
