Part of the reason I have a blog is to document issues and resolutions I do not want to forget. Yesterday morning I was on two calls using Lync and the video was blank or white. I had great audio and messaging worked fine. So the only part that was not functioning was the video. I have been using Lync for years usually the problem was related to connectivity.
I started by leaving and rejoining both calls multiple times. That was primarily just annoying with no change in the video issue. Time to search. So, giving credit to whom credit is due, I found the following blog post by Shay Atik – Lync 2013 Desktop Sharing Shows White Screen. Turns out you need to remove a registry entry related to IE and ActiveX. I am copying the steps that Shay gives here and letting you know it works.
From Shay’s blog:
1. Open the Registry Editor (Start + R -> regedit -> OK).
2. Backup the registry (just in case): File -> Export.
3. Go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\ActiveX Compatibility and delete the {00000000-0000-0000-0000-000000000000} expandable folder.
4. Mission completed. Run Lync desktop sharing, and you’re good to go.
Hopefully this helps someone else, and thanks Shay for posting this.
