Thank you for posting this in Microsoft Q&A.
As Thameur mentioned above, changing the user status for particular user to cloud only is not available at this moment.
However, you can perform below steps which will help you in changing the user status for particular to In Cloud in Azure.
- Move the user (which you want to disable) to non-sync OU in on-premise AD.
- Run delta sync in AD connect tool. This will move the user in Azure to deleted container.
- Now wait for 15-20 mins and move the user from deleted container to user's container in Azure manually.
- This will change the user status to "In Cloud".
This method works but incurs a delay of 10-20 minutes per user while Azure processes the restoration.
Apart from this you can also use the option that Thameur has mentioned above in his answer.
Let me know if you have any further questions.
