I setup Manage License to track how many Microsoft Office 2013 Pro Plus installation we had (these were incorrectly installed by a contractor) so we could begin the process of uninstalling them and install O365 Pro Plus. This worked well and picked up all the computers with the incorrect version installed. It showed me that there were 113 under licensed computers out there.

However, when I do a reconcile I find that there are several computers showing as installed, but they no longer are on our network and they do not feature anywhere else on Desktop Central, in other words they not under inventory or "Scope of Management".

This is obviously giving me an inaccurate report. How do I go about removing these computers from the report to ascertain a more reflective and accurate report I can issue my Technicians to action?
