Outlook Web App Mailbox Policies | Available Settings

OwaLightEnabled

True

This parameter enables or disables the light version of Outlook Web App. When this parameter is set to $false, only the standard version of Outlook Web App is available to users.

Note   If the OwaLightEnabled and OwaPremiumEnabled parameters are both set to $false, users can't access their mailboxes using Outlook Web App in any Web browser. Users will receive the same error that's displayed when they try to open Outlook Web App in an incompatible Web browser.
