Administrators make sure everyone access the Unified Interface and discourage users from using the classic Web UI.

There’s a quick setting to hide the “Dynamics 365 – custom” from the Sidebar for other users. Let’s say users are seeing this currently. And you don’t want the to go there (from the sidebar menu at least).

Change the Visibility

1. Navigate to Settings > My Apps.
   
   Note: In case you don’t see My Apps in your Settings area, here’s a link to my blog for the shortcut to go inside My Apps – My Apps missing from D365 SiteMap
2. Simply select “Hide for All Roles” as shown below. That’s it.
   
3. And this is what others will then see.
   

Easy!
