Error 715-123220 while adding New CSP Customer

Over the past couple of months, this has become a common issue when attempting to add a new customer through the CSP portal using the GUI. After entering the customer details and submitting the form, the CSP admin repeatedly encounters the same vague error message. The error continues to appear despite correcting or re-entering the information, often requiring multiple attempts with slight variations in the address details. In some cases, the customer creation eventually succeeds — but only seemingly by chance rather than as a result of a clear correction. Error Message: We are unable to validate your request at this time. Be advised anonymous connections are not allowed for this service.

After a thorough investigation, it has been identified that the issue is caused by a recent modification made by Microsoft to the new customer creation form, specifically related to address validation. The system now performs strict validation against Microsoft’s internal address database. If there is any mismatch — even minor differences — between the entered Address Line 1, Address Line 2, City, State, or ZIP Code, the system returns a vague or unknown error message. In some cases, CSP administrators may succeed in creating a new customer after multiple attempts using different address combinations; however, this appears to be inconsistent and largely trial-and-error.

The New-PartnerCustomer PowerShell cmdlet is used in the Microsoft Partner Center to create a new customer tenant for Cloud Solution Provider (CSP) partners. As a workaround, I tried this cmdlet for creating new customers. However, the same unclear validation error occurs unless the -DisableValidation parameter is added. Once this parameter is included, the customer creation process completes successfully. Full Command: New-PartnerCustomer [-AssociatedPartnerId <String>] -BillingAddressLine1 <String> [-BillingAddressLine2 <String>] [-BillingAddressCity <String>] -BillingAddressCountry <String> [-BillingAddressPostalCode <String>] [-BillingAddressRegion <String>] [-BillingAddressState <String>] [-ContactEmail <String>] [-ContactFirstName <String>] [-ContactLastName <String>] [-ContactPhoneNumber <String>] [-Culture <String>] -Domain <String> -Language <String> -Name <String> [-DisableValidation] [-WhatIf] [-Confirm] [<CommonParameters>] Example: First open PowerShell and create connection with partner center: Install-Module -Name PartnerCenter Connect-PartnerCenter Collect your customer details, replace customer details in the below example and issue the below command: New-PartnerCustomer -BillingAddressLine1 "400 Rella BLVD STE 207-298" -BillingAddressCity "Montebello" -BillingAddressState "New York" -BillingAddressPostalCode "10901" -BillingAddressCountry "US" -ContactFirstName "Sushil" -ContactLastName "Paudel" -ContactEmail "xxxxx@idreams.ai" -ContactPhoneNumber "xxxxxxxxx" -Domain "idreamsai.onmicrosoft.com" -Language "en" -Name "iDream LLC" -DisableValidation

The -DisableValidation flag indicates whether the additional client-side validation should be skipped.

When -DisableValidation is used:

• Some client-side validation rules are bypassed.

• Certain format validations (postal code, state, etc.) may not block execution.

• Some pre-check API validations may be relaxed.

Therefore, using New-PartnerCustomer -DisableValidation becomes the only practical solution in countries where postal/ZIP code systems and address standardization are not properly implemented or maintained by the government. Microsoft is also advised to add 'Skip Client Side Validation' option in the customer creation form.
