<div>Using ZCS 10 Classic UI, there are two ways to switch to
ModernUI. Either by selecting "Modern Web Client" from the
arrow down menu next to the account name in the top right
corner of the interface (non-persistent way) or by changing
'Default Web App' in user's preferences from Classic to Modern
(persistent change). But neither of these choices are
available in Modern UI to allow a user to switch back either
temporarily or definitively to Classic UI.<br

<div>I've seen this post here [1] where Mark says it's possible.
Do I need to set something in the COS to allow this?<br

<div>BTW, we're using preauth mech for SSO access so users never
see the Zimbra login page (and can't use it to switch back to
Classic UI).</div>
