Hello @Kristiina,
Good day! Thank you for posting your valuable question on Microsoft Q&A forum.
Based on the details you've provided, it appears that this issue requires a deeper investigation on the backend. We recommend reaching out to the Microsoft Technical Support Team for further assistance.
Their specialists can perform deeper diagnostics and, if needed, escalate the case to the appropriate internal team for further analysis. This ensures the issue is formally tracked and may contribute to a future fix.
For Education Support:
- Find your Microsoft 365 admin: If you don't know who the global admin is in your organization, you can find guidance here: How can I find my Microsoft 365 admin? - Microsoft Support
- Submit a service request: The Global Administrator should create a support request with Microsoft to receive advanced technical assistance. For detailed instructions, see: Get support - Microsoft 365 admin | Microsoft Learn
- If your organization's Office 365 Business/Education subscription is from a partner or reseller, and the global administrator is unable to open a service request on your end, contact the reseller's support provider to help open a service request on behalf of you instead.
If you discover any solutions or have additional insights, please consider replying to this thread to help others in the community.
I sincerely apologize for redirecting you to the Microsoft Technical Support Team. While we strive to assist as much as possible here in the forum, our resources are limited when it comes to backend-level diagnostics and advanced troubleshooting. Some issues require deeper technical analysis and access to internal tools that only the official support team can provide.
If you need further assistance, feel free to reply. I'm here and happy to help!
