Lync presence not visible in SharePoint

I got a question from a colleague the other day. He was sad that I could see online presence in SharePoint, but his presence icon was just a white rectangle.

The lync and SP servers are in the same domain, so there should not be any issues related to SIP adresses etc.

After some troubleshooting we discovered that it worked for me because I'd added the SharePoint URL to my Trusted Sites zone. Problem solved!

Dodging silverlight when streaming media from SharePoint 2013

I uploaded a video for my colleagues the other day to our SP2013 intranet.

Some hours later I got complaints that the video required Silverlight to play, which got all our linux and mac users to go home and cry.

Googling for a solution I found several threads talking about user agents, document types, changing browser compability mode etc etc. All of the solutions seemed way to complicated to implement. Why isnt the browser choosing HTML5?


There must be an easier solution out there, I thought.
And surely enough I just had to change the Browser File Handling option to Permissive in Web Application General Settings.



This will skip adding headers to the websites, so that the browser chooses how it should display content.
From IE9 and newer versionis of other browsers aswell, the browser will choose HTML5 over Silverlight.
Great success!
