Hi

I am trying to change my settings for "Window size when screen sharing", but for some reason the settings are disabled and I can't work out why.

Please see my screenshot. how can I change these settings?

Thanks, James

Hi Jamesp,  

The settings are greyed out most likely due to a group policy setting that was setup by your IT department.   These are called MSI settings for a Windows environment.  The specific option pushes the Client to always launch in full screen when joining a meeting.  

Please consider marking this as solution accepted if I have answered your question. 

Thank you,
