[Entra ID Signup] Unable to Access Microsoft Entra Tenant After Signup and Billing Verification Issues

Hello @Eunice Ansah Asare

Hey! Sorry you’re running into this—those two symptoms (billing setup not completing, and then getting blocked from signing into the tenant) often show up together when the tenant’s licensing/access activation for the new Entra plan doesn’t finish successfully or the directory access isn’t activated.

1) About the billing address being rejected

The details we have don’t include specific remediation steps for billing address validation failures. In general, if the signup/subscription flow can’t complete due to billing validation, it can prevent the tenant’s setup from reaching the point where directory access/features are fully enabled.

Practical next step (based on the docs we have):

• Focus on completing the tenant’s licensing/access activation steps (see section #2). If the tenant access isn’t activated, you may be blocked from Entra admin access regardless of having entered billing info.

2) About the sign-in error: AADSTS5000228 / interaction_required

Your error text says:

“Access to ‘<tenant>’ is denied. Please contact your administrator.”

Error code: interaction_required

This aligns with a case where Microsoft Entra ID access for a newly purchased/newly created P1 or P2 licensing plan hasn’t been activated yet, or is not yet provisioned/confirmed.

From the provided documentation:

If you signed up using a new Entra ID P1/P2 license plan

• You must activate your new license plan using the confirmation email Microsoft sends after purchase.
• The process can require a sign-in/verification flow.
• Until activation is completed, you won’t be able to access Microsoft Entra ID for the new tenant.

If you’re adding P1/P2 licenses to an existing subscription

• Entra ID access should already be activated.
• If not, you need to activate it after the Welcome email arrives (two-step verification via a mobile device is mentioned in the doc).

What to do

1. Find the confirmation email (for new license plan sign-up) and/or the Welcome email (for activating Entra ID access).
2. Open the email and select Sign in (or Sign up depending on the email content).
3. Complete the required verification steps (two-step verification using a mobile device is mentioned for the Welcome-email flow).
4. After that, try signing into the Entra admin center again.

3) “I can’t access the tenant to manage settings / create a support request”

If you’re blocked from Entra admin access, the provided docs indicate the key unblock is to complete the activation from the email (confirmation/welcome). That’s the documented way to restore access for newly created/purchased P1/P2 tenants.

Separately (in cases where the problem is actually a lockout due to policy/authenticator issues), Microsoft also recommends having emergency access accounts (“break-glass”)—but that guidance is specifically for tenant lockout scenarios, not licensing activation denial. If your sign-in denial is truly “access denied” tied to the onboarding state, email activation is the most relevant first move.

Follow-up questions (to pinpoint which activation path applies)

1. When you created the tenant, did you subscribe to Entra ID P1 or P2 (or another plan), and was it a new license plan vs adding licenses to an existing subscription?
2. Did you receive a confirmation email after purchase and/or a Welcome email? If yes, which one(s)?
3. Are you able to sign in to the email account that owns the tenant (even if you can’t access the Entra admin portal)?
4. Do you know the approximate time between billing address rejection and when you attempted to sign into the tenant?
5. In the current sign-in attempt, is the blocked tenant your initial onmicrosoft.com tenant (default) or a tenant associated with a custom domain?

If you share which email (confirmation vs Welcome) you received and whether the billing step completed fully, I can help you narrow down the exact activation step to recommend.
