Enablement in Egnyte App Store by Admins

2. Click on Enable Integration: You can enable the integration in multiple ways:

  •  Added for all users: Makes it available to all users
  • Allowed for all users: Makes it available to all users, but the users need to add the integration if they want to use it
  • Added for Groups: Makes it available to specific group of users (who have Microsoft Licenses)

We recommend enabling using the "Added for all" users option.

Set the integration as default app for editing and hit Save.


3. Admins also can set the default option for one-click coediting under the App Control Center tab on the Apps & Integrations page: This is a prioritized list of available co-editing applications whose order can be changed via drag-and-drop. The ranking order sets the one-click default coediting application for users on the Web UI and Egnyte Desktop Apps.


The Admin setup is complete on the Egnyte side.
