Owa Light Mode To Owa Premium

Hi all,

Some users have enabled the OWA light Mode via 'Options \ All Options \ Settings \ General' and they have ticked the box.

My purpose is to "prevent" the use of the Light Mode.

I've found the cmdlet: set-casMailbox -id <identity> -OwaLightEnabled $false.

And it works fine.... BUT!!

After disabling OwaLight Mode, the user cannot access to the OWA even in Premium Mode (due to the option selected previously).

My question is:

for a mailbox onwhich the user has enabled the Owa Light Mode, How can I force the Owa Premium mode?

FYI in the OWA Policy, the Premium is Enabled.

Thanks for your help

Mykel
