Hi @Bc. Jakub Hruška

Thank you for posting your question in Microsoft Q&A.

Please understand that our forum is a public platform, and we will modify your question to cover your organization domain name in the description. Please notice to hide these personal or organization information next time you post error or some information to protect personal data.

First of all, we regret for the inconvenience caused to your work. Based on your description, it appears that your tenant has encountered an issue while attempting to access Outlook Web App (OWA).The TenantAccessBlockedException error usually indicates that your Microsoft 365 tenant has been blocked, often due to an expired subscription, billing issues, or specific policy violations.

If it possible could you try to:

Verify Subscription Status: This error can occur if the Office 365 subscription has lapsed or wasn’t properly maintained. Log into the Microsoft 365 admin center using the admin account to check your subscription status and ensure that it is active.

Check compliance or policy violation: Since your account setup is Global Admin, could you check and verify the configuration and resolve any access restrictions.

Contact Microsoft Support: According to your issue, to help you verify and unblock your tenant, I suggest you raise a support ticket from the Microsoft 365 admin center, where the related team can perform a remote session to investigate the situation, verify the backend configurations, and run any necessary synchronization tools to resolve the problem.

If the issue requires further attention, they can escalate it to a specialized team for deeper analysis.

You can refer: Get support - Microsoft 365 admin | Microsoft Learn

Call Microsoft Support: For additional assistance, use this link to find the appropriate contact number: Customer service phone numbers - Microsoft Support

Apologies for redirecting you to the related development team support as forum moderators, we don’t have access to the detailed system needed to troubleshoot this effectively due to privacy and security constraints. We recommend contacting Microsoft’s support team directly, as they are best equipped to address and resolve this type of issue efficiently.

We hope this information is helpful and appreciate your understanding.

If you have any additional concern, feel free to comment below. I be more than happy to assist.

Hello,

I understand, it has been due to security incident in half of July. We already corrected everything on our side, last thing which we are not able to solve is unblocking the tenant. I found thread here in the forum, where it was done from Microsoft side based on request posted here (https://learn.microsoft.com/en-us/answers/questions/2283276/aadsts5000224-tenant-access-is-blocked).
I already contacted support in the middle of July, but so far, I do not have any feedback on the topic!

Thanks!

Jakub

Also I would like to note that our users can not login into their mailboxes and Teams, because of the blocked tenant for more than month! No feedback from MS support at all to my requests from middle of July! Only thing I need is to unblock the tenant!

If not unblocked, data of all users will be deleted on 13th of August!!!

Hi @Bc. Jakub Hruška

Sorry for my delayed respond.

As a forum moderator, I do not have access to the administrative tools required to resolve this issue due to privacy and security restrictions.

To help unblock access to your tenant, please consider reaching out to Microsoft Support. If possible, could you let me know whether you've already submitted a support ticket or contacted them via phone?

Could you please confirm whether you still have access to the Microsoft 365 admin center

Also, have any support agents been assigned to your case, or is your request still pending?

Any update would be appreciated.

We understand this situation can be frustrating, and we truly appreciate your patience. I would try my best to assist you.

Warm thanks.

Hello,

I am trying to solve the situation with MS support, but I created several tickets without any feedback and action, our tenant is blocked for more than month and a half now and more than 400 users can not work - how is this possible??????
Does anyone in the whole Microsoft care about their customers??????

I did not see such level of incompetency anywhere ....

I created several tickets also with my local partner and provider, but nothing happened at all. I think the whole Microsoft is making fun of their customers with such a horrible approach.

From the half of Jully, totally no action at all??????

I am trully sick of the MS support approach which did not nothing past month and half, totally do not care that 400+ users can not work at all ...

I created several tickets and made hundreads of phone calls so far, but with no result.

Hi @Bc. Jakub Hruška

Thank you for your responding.

I sincerely empathize and understand that this issue may be affecting your current tenant.

As a forum moderator, I’m here to help guide discussions and share information based on Microsoft documentation and community knowledge, but I don’t have access to internal product insights or the ability to give the precise answer from a developer perspective.

Since this issue could lead to a negative affection on your tenant in long-term, I’d recommend you to raise a Unified Support ticket.

You can refer: Unified Support (Paid support ticket)

You could follow these selection below to reach out to Unified Support teams

Please understand that this solution is intended to help you connect with the professional support team. They will acknowledge your request and reach out to you as soon as they receive the ticket. Since this issue could lead to data loss or disrupt your tenant’s workflow, I recommend proceeding with this approach.

I truly appreciate your patience and understanding.

Warm thanks
