Due to this popup i am not able to delete the Organization in orchestrator.
Hi @Rizwana_KM
You can’t delete an organization if there are active sessions or running jobs tied to it. pls check some sessions are still active. Stop or disconnect those sessions first, then try deleting again.
If helpful, mark as solution tick.
Happy automation with UiPath
It means Orchestrator is still in use first ensure all the jobs are stopped, remove disable robots. Then retry deleting. If the issue persists then sign out and then again sign in and then try deleting.
If this is needful then mark it as SOLUTION
Happy Automation
I have deleted the tenants
Still the same issue or the organization is deleted
If same issue then sign out of orchestrator and agin sign in to orchestrator then go to admin → settings → advanced → delete organization try to delete again.

Go to settings and go to advanced then delete the organization. If still the issue persists then sign out and then sign in to orchestrator.
I also tried the same but I deleted the organization but mine was demo which i created now.
See the screenshot it is of my mobile because I don’t have my laptop now with me
It could be an intermittent error.
You could perhaps wait a few days and see if it lets you delete it. Long term if it cannot be done perhaps contact UiPath support and request they delete it for you?
Hey Rizwana wait for few time if the issue persists then you can simply raise a ticket to UiPath using this and mention your problem with screenshot if applicable.
