Installing the Outlook Add-In


Installing the add-in

For FileCloud admins

Central deployment
As an admin, you can deploy the add-in centrally using the Microsoft 365 Apps admin center. This enables you to control who has access to it, and to remove or add access at any time. In addition it enables you to automatically insert the add-in into the users' Outlook ribbon, eliminating the requirement that they install it themselves. 

To deploy the add-in centrally, see the Microsoft 365 Apps admin center.

User download
The add-in is also available from the Microsoft Office store for individual users. You can allow users to install the add-in from there, but you are not able to manage it centrally if they download it this way.  User steps for installing the add-in are listed below under For FileCloud for Outlook users.

For SSO login

To be able to log in with SSO, users must also have the Auth Agent application running on the client they are using to access Outlook. 
To install and run the SSO Auth Agent, see Install and Run the SSO Auth Agent .


For FileCloud for Outlook users

Check with your admin whether FileCloud for Outlook is available to you already when you click the Apps icon  AppsIcon.png in Outlook, or if you need to add it yourself.
