For those who are running the 2013 Office server wave (Exchange, Lync or SharePoint), you may have to deploy Office Web Apps 2013 to get full functionality (such as with Lync for online meeting and media sharing)

Good news, Microsoft has published the technical library in compiled CHM file for offline use ( as it has been done for SharePoint 2013).

You can download it from http://www.microsoft.com/en-us/download/details.aspx?id=30387

As reminder, the SharePoint 2013 CHM file is available from http://www.microsoft.com/en-us/download/details.aspx?id=30382 and the one for Office 2013 is here http://www.microsoft.com/en-us/download/details.aspx?id=30389
