SharePoint and OneDrive blocked by PolicyViolationThrottle — Microsoft 365 Developer Program tenant — existing data recovery

Question

SharePoint and OneDrive blocked by PolicyViolationThrottle — Microsoft 365 Developer Program tenant — existing data recovery

Muhammad Ans 0

Hello Microsoft Support/Community,

I am using a Microsoft 365 Developer Program E5 sandbox tenant:

Tenant/domain: 05g8m.onmicrosoft.com

SharePoint hostname: 05g8m.sharepoint.com

OneDrive hostname: 05g8m-my.sharepoint.com

Developer Program account: [[Moderator note: Personally Identifiable Information removed] @outlook.com]

Sandbox administrator: [[Moderator note: Personally Identifiable Information removed] @05g8m.onmicrosoft.com]

For approximately 6 months, SharePoint and OneDrive have been inaccessible.

When I open OneDrive, it redirects to:

PolicyViolationThrottle.htm#1033

I also receive ERR_TOO_MANY_REDIRECTS.

The SharePoint Admin Center is also inaccessible and redirects to the same PolicyViolationThrottle page.

Other Microsoft 365 services, including Microsoft 365 home and Copilot, are accessible normally with the sandbox administrator account.

I checked Microsoft 365 Service Health and there is no SharePoint/OneDrive incident reported for this tenant.

I have also tried accessing the services from different browsers, but the issue remains.

The most important concern is that I have important existing data stored in SharePoint/OneDrive. I do not want to delete, recreate, or reset the tenant, users, or OneDrive. I need to preserve the existing data.

Could Microsoft please investigate the backend status of this Developer Program tenant and confirm:

Why SharePoint and OneDrive are being blocked by PolicyViolationThrottle.

Whether the existing SharePoint/OneDrive data is still preserved.

Whether the restriction can be reviewed or removed.

What official process I should follow to regain access to the existing data.

I am the administrator of the Developer Program sandbox and can provide additional tenant verification information if required.

Thank you.

Hello @Muhammad Ans,

Thank you for providing the detailed information.

Based on the symptoms you described, this appears to be a SharePoint Online/OneDrive service-level restriction rather than a browser, device, or authentication issue. The behavior you are seeing, including redirection to PolicyViolationThrottle.htm#1033, ERR_TOO_MANY_REDIRECTS, and inability to access the SharePoint Admin Center, generally indicates that SharePoint Online access has been restricted by a backend policy or compliance enforcement mechanism.

Unfortunately, the Microsoft Q&A community does not have access to tenant backend information and cannot determine:

The specific reason the restriction was applied.
Whether the restriction was triggered automatically or manually.
The current retention status of the SharePoint Online or OneDrive content.
Whether the restriction can be lifted for a particular tenant.

Regarding your most important concern, the presence of a PolicyViolationThrottle page does not by itself confirm that your data has been deleted. However, only Microsoft Support team can confirm the actual retention status of data for your specific tenant.

Given that your objective is to preserve and recover existing data rather than recreate the tenant, I recommend pursuing an official support investigation: Get support - Microsoft 365 admin | Microsoft Learn

If your subscription is from a partner or reseller, contact the reseller's support provider to help open a service request on behalf of you instead.

I hope this information helps point you in the right direction. If you receive any updates from Microsoft Support regarding the status of the restriction or data recovery options, please consider sharing them here for the benefit of the community.

Kind regards,
