Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Dear PBX Technologies,
Thank you for providing the details of your situation. I fully understand the urgency, particularly as the inability to access your Microsoft 365 administrator account is affecting your business operations.
As you already have an active Microsoft Support case, I recommend continuing to work directly with the Support Engineer assigned to your case. Although the case is currently categorized as Severity C, this does not mean that you should discontinue working with the assigned engineer on the underlying sign-in and administrator access issue.
Please continue to provide the support engineer with the latest troubleshooting results and clearly communicate the current business impact, including your inability to access the Microsoft 365 Admin Center and perform essential administrative tasks. You may also request that the engineer review the case severity and advise you of the most appropriate escalation path based on the circumstances and impact of the issue.
As this is a community support forum, I am unable to modify the severity of an existing Microsoft Support case from Severity C to Severity A. Therefore, continuing to work through your existing support case is the most appropriate course of action rather than creating a duplicate case.
I sincerely hope your administrator access can be restored as soon as possible. Greatly appreciate again for your patience and understanding.
