Apologies for quite a delayed response, I have just returned from a visit to Bodrum (very entertaining and lively) so currently playing catch-up to life!

Whilst I was away, several updates have been released, which are summarised below:

Of significance, is the inability to install CU5 on any Lync Servers that have only the Core Components and/or Administrative tools installed, as pointed out by Greg in this post Lync Server 2013 CU5 OcsCore Update Fails and also confirmed by Microsoft in KB2993188
