A fully managed end-to-end service for digitally signing code, documents, and applications. (formerly Trusted Signing)
The verification link must be opened while signed in with the same email address entered for the person performing identity validation; because your primary contact differs from your personal Microsoft account, use an identity whose sign-in name exactly matches that request email.
Complete the existing request
- Determine the exact Primary Email stored on the existing validation:
- Azure portal → Artifact Signing account → Identity validations → select the validation.
- Also check the mailbox that received the verification link.
- Ensure that exact address is usable as a Microsoft sign-in identity. If the company mailbox is only an email alias or shared mailbox, ask the company’s Entra administrator to create or identify a user whose sign-in address matches it exactly.
- Sign out of all Microsoft sessions, then open the verification link and authenticate as that matching identity—not as the personal Microsoft account guest.
Microsoft documents that “You don't have permission to access this page” occurs when the email entered in the identity-validation request differs from the email used to sign in. This rule applies to individual validation, including the individual-verification stage within organization validation.^1^
The company-domain mailbox being different from your Azure sign-in is therefore material. Owner and Artifact Signing Identity Verifier permissions authorize Azure resource and validation-request management; they do not substitute for the matching identity expected by the verification link. Owner itself does not manage identity validation, while Identity Verifier does.^2^
Tenant and native-account limitations
The public documentation does not expose a way to inspect the tenant embedded in an existing credentials.microsoft.com transaction, force the link to another tenant, or rebind that transaction to another identity.
It also does not explicitly state that this organization-verification step always requires a native member rather than a guest. The documented requirement for this particular permission error is the exact email match. A separate accepted Q&A answer reports that personal Microsoft accounts are unsupported for the signing client’s interactive authentication, but that signing-client case does not establish how an existing organization-validation link can be rebound.^3^
If the matching company address is a native work or school account, use it directly. If it still lands in Microsoft Accounts, or the address cannot be made into a matching sign-in identity, the existing request requires service-side investigation rather than more RBAC or browser changes.
Escalate without deleting the validation
Open an Azure support request from Azure portal → Help + support → Create a support request, selecting Artifact Signing and identity validation. Microsoft explicitly directs identity-validation issues to Azure Support or Microsoft Q&A and warns that creating additional concurrent requests for the same entity does not help.^1^
Ask support to confirm privately:
- The Entra tenant ID associated with the existing validation.
- The exact sign-in identity/email expected by its verification transaction.
- Whether the transaction can be corrected or reissued against the matching native company account.
- Whether the existing validation can continue without creating another request.
- Whether the displayed Microsoft Accounts tenant indicates an incorrect authentication binding.
Provide privately—not in the public Q&A thread:
- Subscription and Artifact Signing account identifiers.
- Identity-validation ID and current status.
- Target Entra tenant ID.
- Object ID and user type of the personal-account guest.
- Exact primary email, expected work-account UPN, timestamp, and screenshots.
- The full error/incident or correlation identifier, if displayed.
Do not delete the current validation while support investigates. Deleted identity validations cannot be recovered and deletion can stop renewal for linked certificate profiles.^4^ The quickstart also says that changing validation information after creation requires a new request, so there is no documented portal edit operation for replacing the email on the existing request.^5^
A Q&A moderator cannot safely determine the expected tenant from public information alone. Posting the validation ID publicly is unnecessary; account-specific inspection must occur through a private support channel.
