Billing Microsoft Customer Agreement (MCA) Account ownership / Subscription access

Hi @Developer Mika Based on the symptoms you described, the most probable cause is a permissions and directory-context gap rather than any loss of your subscription or resources. When a subscription's Microsoft Entra directory association changes, all role assignments in the source directory are permanently deleted and cannot be restored; the subscription, its resource groups, and its management groups are unaffected, and Azure services continue running throughout an MCA billing transition. The result is a subscription that is intact but invisible to your identity. A second, very common contributor: MCA binds to your work or school account, and if the same email address also carries a personal Microsoft account, signing in with the personal one returns an empty view.

Could you please follow the steps below and verify:

Step 1: Confirm your billing account type. Azure portal → Cost Management + Billing → Properties; with multiple scopes, use Billing scopes and read the Billing account type column. Why this matters: it confirms the MCA troubleshooting path applies to your account at all. How to verify: the Type field reads "Microsoft Customer Agreement."

Step 2: Enumerate every directory. Upper-right account menu → Switch directory → in the Directory + subscription pane, select each directory in turn. Why this matters: the MCA-created directory is the most likely host for your subscription, and the portal does not switch context automatically. How to verify: the subscription and MCA billing account appear in Cost Management + Billing under one of the directories. Please record which directories you see, and whether the subscription surfaced.

Step 3: Sign in with the work or school account in an InPrivate browser window. Why this matters: MCA uses the work/school account; InPrivate prevents silent SSO into a personal account on the same email address. How to verify: the upper-right account tile shows the work/school UPN and the expected tenant name.

Step 4: Grant yourself the billing role (if you hold Entra Global Administrator). Cost Management + Billing → Billing scopes → tick view all billing accounts → select the MCA billing account → Access control (IAM) → Add → role Billing account owner → select your user → Save. Why this matters: MCA operations require an explicit billing role; Global Administrator alone does not confer it, and elevation is the documented self-service path. How to verify: after re-authenticating, your identity is listed as Billing account owner and the billing account appears without the "view all" box ticked.

Step 5: Accept billing ownership if the subscription is genuinely orphaned. Where a subscription has no valid billing owner, Azure emails all billing account owners and subscription owners a link to accept ownership and displays a banner on the subscription details page. Why this matters: without a billing owner, no one can view or pay bills; the documented progression is past-due → disabled for nonpayment → eventual deletion, which would affect every service on the subscription. This step is time-sensitive. How to verify: the banner clears and a billing owner resolves for the subscription.

Step 6: Re-create the destroyed access. Subscription → Access control (IAM) → Add role assignment → Owner → your identity; then re-create custom roles and managed identities. Why this matters: the directory move deleted these permanently, and Owner is required for subscription-level management. How to verify: the subscription lists under Subscriptions and its resource groups enumerate.
