Microsoft 365 Developer tenant blocked due to AUP – OneDrive read-only, risk of data loss

Question

Microsoft 365 E5 Developer tenant.

The tenant has been flagged for a violation of the Acceptable Use Policy.

Current state:

• OneDrive is accessible but completely read-only
• Cannot upload, edit, or delete files
• SharePoint Admin Center shows warning about service deactivation
• Data (~1 TB) is still accessible for download but at risk of being blocked

Support case was opened via Microsoft 365 Admin Center (case number: [Moderator note: personal info removed]), but we were redirected as this falls under Developer Program support.

Issue:

Developer Program support portals are currently unavailable and there is no direct way to contact the Developer Program support team.

Request:

• Immediate review of tenant status
• Clarification of violation
• Temporary restoration or preservation of OneDrive access to allow data recovery

This is time-sensitive due to potential loss of access to OneDrive data.

Hi @Tayyab Tavvagunta   

I fully understand your frustration regarding your E5 tenant being marked under the Acceptable Use Policy. 

Regarding your request, I would like to share that this is a user‑to‑user forum, which serves as a space for community members to exchange insights and experiences. We do not have direct access to internal systems or the ability to take action on tenant‑level enforcement. 

That said, to better understand your situation, may I kindly clarify one point? When you mentioned that support for the Microsoft Developer Program is unavailable, could you share additional details such as which portal or link you are using and any message or notification that appears? This information may help others better understand your experience. 

One official way to reach the Microsoft Developer Program support team is through the Report errors option located at the bottom of the Developer Program dashboard. Using this option allows you to send a message directly to the Microsoft Developer Program support team for further review. 

 

I hope this provides some additional insight.

The tenant is blocked at the service level due to an Acceptable Use Policy (AUP) violation, which is why SharePoint and OneDrive are read-only and show deactivation warnings. This matches the documented behavior when Microsoft detects prohibited activity under the Acceptable Use Policy for Microsoft Online Services.

The only supported path to restore access is through Microsoft support escalation; this cannot be fixed from tenant-side configuration.

Actionable steps based on the documented behavior and similar resolved cases:

1. Confirm this is an AUP block (not a normal lock/read-only state)
   • The generic read-only errors (for example, “This site is read only at the site collection administrator's request” or “SharePoint sites are read-only right now while we do some maintenance”) can sometimes be caused by site lock or site policies and can be fixed by changing the lock state or site closure policy.
   • In this scenario, the banner and farm-level/read-only behavior combined with an AUP violation notice indicate a service-level restriction by Microsoft, not a site policy or lock that can be changed in the admin center.
2. Use the AUP-specific support entry point from the Microsoft 365 admin center
   • For AUP-related blocking of SharePoint/OneDrive, the documented resolution is to submit a support request via the dedicated SharePoint Acceptable Use Policy page in the Microsoft 365 admin center.
   • In the Microsoft 365 admin center, go to the SharePoint Acceptable Use Policy page and select Contact support to submit an AUP review request for the tenant.
   • Clearly state that:
     • The tenant is a Microsoft 365 E5 Developer tenant.
     • SharePoint and OneDrive are read-only due to an AUP violation banner.
     • Data is still accessible but at risk of being blocked.
     • A prior support case was redirected as “Developer Program support,” and Developer Program portals are currently unavailable.
3. Escalate through support until a backend team reviews the AUP flag
   • From similar cases, front-line or AI responses may initially suggest local configuration checks (quotas, library settings, permissions). These do not apply when the block is at the service/farm level.
   • Request explicit escalation to the internal backend or compliance team that handles AUP enforcement for Microsoft 365.
   • Provide:
     • Screenshots of the AUP banner and read-only messages.
     • Confirmation that all sites and OneDrive are read-only.
     • Approximate data volume at risk (~1 TB) and the time sensitivity.
4. Clarification of the violation and data preservation
   • The AUP article states that the block occurs when Microsoft detects activity prohibited by the Acceptable Use Policy.
   • In a documented case, support could not immediately identify the exact trigger during the first session and escalated to a backend team. Expect that:
     • The specific trigger may only be visible to internal teams.
     • A detailed explanation may require escalation and additional time.
   • In the support request, explicitly ask for:
     • Confirmation of whether the tenant is scheduled for deactivation and on what date.
     • Temporary restoration of write access or at least extended read-only access to allow full data export.
5. If completely blocked from normal support paths
   • If the standard admin-center support path is not working because of the Developer Program routing, use the same pattern as in similar lockout/tenant issues:
     • Work with Microsoft support (via phone or another tenant, if necessary) to open a ticket that explicitly targets the AUP block on this developer tenant.
     • Make clear that the issue is tenant-level AUP enforcement, not a normal configuration or billing problem.
6. During the review window
   • As long as read-only access remains, download and back up as much critical data as possible.
   • Prioritize irreplaceable content in case the block progresses to full access removal.

The key point is that AUP-triggered read-only and deactivation warnings are enforced by Microsoft and can only be reviewed or lifted by Microsoft support via the AUP/SharePoint route and backend escalation. Local admin actions (changing lock state, site policies, quotas) will not resolve this state.
