Upcoming Restrictions on Public Certificates

A restriction to public certificates was introduced several months ago that could affect your planning of a Microsoft Lync, Exchange, or other application service deployment. While this change restricts only public certificates that contain an internal name with an expiry date after November 2015, you should be aware of this change for planning and certificate renewal purposes.
The Change: No Public Certificates with Internal Names Allowed

Lync 2013 with Office Web Apps Server

After instalation of the Office Web Apps Server and integration with Lync 2013 you might find out that Lync 2010 clients can upload and view powerpoints but Lync 2013 clients do not.

You might see this error on the Lync FE:

Syncing Office Web Apps Server with legacy presenters failed, newer clients may have lost sync for PowerPoint presentations driven by the legacy clients.
 Last attempted Url: https://WebAppsFQDN/m/present_2_0.asmx
Microsoft documentation says you need to install these:

Add-WindowsFeature Web-Server,Web-Mgmt-Tools,Web-Mgmt-Console,Web-WebServer,Web-Common-Http,Web-Default-Doc,Web-Static-Content,Web-Performance,Web-Stat-Compression,Web-Dyn-Compression,Web-Security,Web-Filtering,Web-Windows-Auth,Web-App-Dev,Web-Net-Ext45,Web-Asp-Net45,Web-ISAPI-Ext,Web-ISAPI-Filter,Web-Includes,InkandHandwritingServices

But there's a few features missing for this to work

Add-WindowsFeature NET-Framework-Features, NET-Framework-Core, NET-HTTP-Activation, NET-Non-HTTP-Activ, NET-WCF-HTTP-Activation45
Add this ones, restart the Office Web Apps service and everything should be working now!
