Hi,
Azure tenant inactive for 90 days without access or usage may be disabled and marked for deletion by Microsoft, leading to a loss of data and service access. To resolve this, you may need to make a purchase, add a valid payment method in the Microsoft 365 or Entra admin center, or create a support request to regain access. If the tenant has not been blocked for more than 20 days, you may be able to reactivate it; after this period, it will be permanently deleted. and to discuss the issue you will need to call up global support desk - https://support.microsoft.com/en-us/topic/global-customer-service-phone-numbers-c0389ade-5640-e588-8b0e-28de8afeb3f2
Hope this helps.
