Title: Some admins may be unable to enable Organization Customizations in the Exchange Online admin center and PowerShell
User impact: Admins may have been unable to enable Organization Customizations in the Exchange Online admin center and PowerShell.
More info: Affected admins may have seen the error “Enabling customization is not allowed because the Organization is currently being upgraded. Please try again.” when using the Enable-OrganizationCustomization cmdlet in Exchange PowerShell.
Final status: We’ve confirmed that our additional fix to prompt the service to upgrade, which was necessary for affected admins to receive the fix for the underlying issue, has completed. We’ve verified via telemetry capturing this impact scenario that the issue is resolved.
Scope of impact: Impact was specific to admins who attempted to enable Organization Customizations in Exchange Online. The problem occurred if an organization had been recently migrated or was being migrated.

Root cause: A recent standard service update introduced a code regression that was blocking the Organization Customization enablement cmdlet.
Next steps:
– We’re reviewing our standard service update processes so we can better identify similar code regressions during our testing cycles and avoid comparable impact in the future.
This is the final update for the event.
