Title: Some admins may be unable to enable Organization Customizations in the Exchange Online admin center and PowerShell
User impact: Admins may be unable to enable Organization Customizations in the Exchange Online admin center and PowerShell.
More info: Affected admins may see 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.
Current status: Our additional fix to prompt the service to upgrade to the newest build and receive the fix for the underlying issue has completed in the vast majority of the affected environment and provided relief for most admins. We’re monitoring as it continues to saturate the remaining portion of the affected environment, which is taking more time than previously estimated. We now anticipate that this will complete and fully remediate the issue by our next scheduled update.
Scope of impact: Impact is specific to admins attempting to enable Organization Customizations in Exchange Online. The problem occurs if an organization was recently migrated or is currently being migrated.
Start time: Tuesday, August 29, 2023, at 4:55 AM UTC
Estimated time to resolve: We anticipate that impact will be fully remediated by Wednesday, September 19, 2023.
Root cause: A recent standard service update inadvertently introduced a code regression that’s blocking the Organization Customization enablement cmdlet.
