- Product
- Microsoft SharePoint
- Device & OS
- not provided
- Scenario
- Managing an existing SharePoint site where a setup or enrollment wizard continuously pops up.
- Observed behavior

Ensure you have your Microsoft 365 administrator credentials or know who your organization's IT administrator is, as resolving this issue requires admin-level access to open a support request.
Open a Microsoft Support Request via Admin Center
Because the enrollment option is stuck on a loading screen, this indicates a backend server issue that requires Microsoft's technical support to collect logs and resolve.
Adjusting standard site creation settings will not fix a stuck loading screen on an already existing site. Microsoft 365 support must investigate the server-side logs to unblock the enrollment wizard.
Have your Microsoft 365 administrator sign in to the Microsoft 365 admin center using their administrator credentials.
On the left navigation menu, click on 'Support' and then select 'Help & support' or 'New service request'.
Describe the problem specifically, mentioning that 'Exclude the site from enrollment' is stuck loading on an existing SharePoint site, and submit the ticket so the support team can collect the necessary logs.

Frequently Asked Questions
Will disabling site creation remove the new-site wizard?
No, navigating to the SharePoint admin center and disabling 'Let users create sites' only stops users from creating new sites. It typically does not remove a stuck wizard on an already existing site.
Why is the 'Exclude the site from enrollment' screen stuck loading?
A stuck loading screen during this process is usually caused by a server-side bug or synchronization issue within Microsoft 365, which requires Microsoft support to investigate via backend logs.
Can a standard SharePoint user fix this wizard issue?
No, standard users do not have the required permissions to resolve backend errors. You must contact your Microsoft 365 administrator to open a support request in the admin center.
