Block Flow usage

So I understand that it is impossible to desactivate Flow for users because they can always use the free version. However, can a company block users from manipulating its own company data (SharePoint, Outlook, ...)?


Hi @KTNN0 


You can also revoke the free license from the office admin panel I believe. 


For SharePoint, you have this powershell commandlet as mentioned here to disable flow.


For Outlook, the user will only be able to access their own emails/ events etc for manipulation. If you could share more details on this, we might be able to assist you better. 


Hope this Helps!

Thank you for your answer. I'm getting more and more convinced that it's impossible to prevent users to work with Flow:
What is the Microsoft Flow Free Plan?
The Microsoft Flow Free Plan is used only for tracking purposes. Enabling or disabling it has no effect on a user's ability to create flows. If you disable the Microsoft Flow Free Plan, it becomes enabled again when a user logs in. This is the expected behavior.

Hi @KTNN0 ,


I assume that the following doc could be a reference for you:


About how to restrict the use of organizational-only data inside of Microsoft Flow, it is possible though Data loss prevention policies. More details about DLP please check it at here:

I suggest opening a ticket with Microsoft on this.  I believe that you can block Flows from being created from outside of your tenant (such as with a free license) which access data in vour environment but this can only be done via a ticket.

As of 12/19 you can block all trial licenses in O365


I'd try that to see if it helps your issue.
