When you experience problems sharing PPT content in a Skype for Business meeting, the reason could be a variety of different factors not beeing implemented in the correct way.
There are many ways to publish the Office Web App server necessary to enable this feature. One of those are the IIS ARR web proxy.
In this case the proxy is set up and everything is working fine with all web services, and the officewebapp URL test(https://officewebapp.yourdomain.com/hosting/discovery) is also returning the correct XML page. However, when an internal user uploads a PPT to the meeting, the federated participant experiences just a spinning “Loading” and the presentastion does not load correctly in the client. Other internal users are able to see the presentation in the meeting.
Remove response header added from IIS on Revers Proxy server, Open Internet Information Services (IIS) Manager on IIS ARR server.
- In the Connections pane on the left side, expand the Sites folder and select the site(Default Web Site).
- Double-click the HTTP Response Headers icon in the feature list in the middle.
- Highlight “X-Frame-Options” In the Actions pane on the right side, click Remove.
- Click OK to save your changes.
- Run iisreset from an elevated commandprompt.
After Removing the X-Frame-Options the presentations renders perfectly from the OfficeWebApp server for external participants as well.

This is a great post done by Skype4B enthusiast Mark Vale on Cloud PBX and Office 365 E5 which is to be launched in the US on December 1st 2015. I recommend everyone to read his thoughts and keep them in mind.

Incredibly useful post by Mark Vale(@unifiedvale) on how to recover from a corrupt CMS. Please do note the points in the article about making a backup of your Lync environment. You never know when you need it.

Implementing backup of your Lync/Skype for Business environment can be accomplished in many ways. Please check out MVP Lasse Wedoe’s blog on how to as one of several resources.
In a short period of time I’ve encountered two different cases of the Edge server not replicating. Everything seems OK, but the changes simply won’t move to the Edge.
I found a great blogpost by Jaap Wesselius here that describes the exact problem and how to fix it.
Simply add the following to the registry of the Skype/Lync Edge server:
New REG_DWORD(32bit) ClientAuthenticationTrustMode with value “2” in HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\SecurityProviders\SCHANNEL
Restart the Edge server(not just the services) and toggle the Skype/Lync replication service on the FrontEnd server. Wait a few and the replication should be OK.
