How do I temporarily take all CRM Online users offline?

Question

I need to prevent all CRM Online users from logging in for a short period time while I perform an upgrade to some of the customizations.

Disabling each user is time consuming and I believe that disabling will require a new "invitation" after the user is re-enabled.

What is the best approach for this?

Answer 1

I would suggest trying to disable the Business Unit. But you cannot do this if you only have one Business Unit defined.

According to the online documentation above, disabling the BU will disable login for all users. We would have to deduce a suitable methodology for managing this, for instance having a single user in a second “administrative” BU that you would login as that user to manage this process.
