Question

New Microsoft 365 Business Premium trial tenant is read-only: "Tenant sites are in read-only right now"

Jiří Škába 0

Our Microsoft 365 Business Premium trial tenant was created on 30 Oct 2026. Since then no SharePoint site can be created: Graph create site returns 500, a Microsoft 365 group site has been stuck in provisioning since 4 Nov, and creating a communication site in the browser fails. Creating a folder in the existing team site shows "Tenant sites are in read-only right now". OneDrive sync fails with "not enough space", although the OneDrive quota is 1 TB and only about 400 KB is used. The whole tenant uses about 14 MB. Service health shows no incident. In the admin center the button to start the paid subscription now is greyed out, and the Support Assistant does not offer a way to open a service request. Is the read-only state caused by the trial, and how can it be removed? Please escalate to the SharePoint Online team. I can send the tenant ID privately.

Did you get this resolved? I have exactly the same issue with a Business Premium trial, and we also started that around 29th October.

Hi Jiří,

You can verify the issue by runnning the admin center self-help diagnostics: Self-help diagnostics for SharePoint Online and OneDrive administrators - SharePoint | Microsoft Lea…

To check the status of each site, run:

Get-SPOSite -Limit All | Select Url, LockState, StorageQuota, StorageUsageCurrent

If the admin center shows the new quota, usage is comfortably under it and the sites are still read-only after a couple of days, open a support case with those figures and ask whether a service incident applies.

Please contact Microsoft Support and request guidance with the account-to-account migration process through the Microsoft 365 Admin Center.

Here are some tips for creating support tickets more effectively:

Go to Microsoft 365 admin center > Support > Help & Support.
Turn off the "Support Assistant" feature.
Use the keyword "Support" to quickly bypass automated suggestions > Select Contact Support.
In the ticket description, please provide a clear and detailed explanation of the issue. You may also attach relevant screenshots or screen recordings.
Additionally, sharing your preferred contact times can help the support team handle the case more efficiently.

I hope this information is helpful. If you have any questions or need further support, please don’t hesitate to reach out at any time.

Thank you for your patience and understanding.
