Microsoft.Exchange.Data.Storage.TenantAccessBlockedException after paying DUE Azure Subscription

Exchange Online and Microsoft 365 services are tied to your Microsoft 365 tenant, not directly to the Azure subscription. This error usually occurs if:

1. Your Microsoft 365 subscription (Exchange Online, M365 E3, etc.) was temporarily suspended due to non-payment or past-due status or you have paid the bill, but the payment has not yet propagated across Microsoft’s backend systems (can take up to 24 hours).
2. The tenant status is still showing as “Disabled” or “Suspended” in the Microsoft 365 admin center. Sometimes, if you recently moved from a trial to a paid plan, the Exchange service provisioning can get stuck.

If the tenant still shows blocked:

1. Run the following PowerShell (from an admin account): Verify if your SKU (license) is Active.

      Connect-MsolService
      Get-MsolAccountSku
      
   

   • Run:
   • Set-MsolUser -UserPrincipalName ******@domain.com -BlockCredential $false
   • This unblocks the user (if individual account was locked).
2. If the tenant is blocked due to billing hold, you must contact Microsoft 365 billing support.
