Login Azure failed...

Question

My Microsoft account works fine, but I can't log in to Azure, Error Message:

Pick an account

Selected user account does not exist in tenant 'Microsoft Services' and cannot access the application <PII info> in that tenant. The account needs to be added as an external user in the tenant first. Please use a different account.

Answer 1

just to confirm… you’re not actually trying to access the Microsoft‑Services tenant… if not, the portal mis‑routed your MSA there—open a private window → portal.azure.com → Switch directory → pick the tenant that owns your sub and it signs in clean.

Answer 2

The error means the Microsoft account being used does not exist in the target Microsoft Entra ID tenant (“Microsoft Services”) and therefore cannot access the Azure application in that tenant.

To resolve this, use one of these approaches depending on what is needed:

1. Sign in with the correct tenant/account
   • If there is another work or school account that actually belongs to the “Microsoft Services” tenant, sign out of all Microsoft sessions and sign in again with that account.
   • If multiple accounts have the same alias (for example, a personal Microsoft account and a work account with the same email address), explicitly choose the work/school account when prompted.
2. Ask the tenant admin to add the account as a guest
   • If access to that specific tenant (“Microsoft Services”) is required with the current Microsoft account, the administrator of that tenant must invite the account as a guest user in their Microsoft Entra ID.
   • After the admin adds the account as a guest and the invitation is accepted, sign out and sign in again to access the application.
3. Check for wrong tenant or stale session
   • The browser may be using an existing session for the wrong tenant or identity provider.
   • Sign out from all Microsoft accounts, then open a private/incognito browser session and try to sign in again with the intended account.

If there is no account in that tenant and no admin to invite the account as a guest, that tenant’s Azure resources cannot be accessed with the current Microsoft account.

Answer 3

Hey Little Wing, it looks like you’re signing in with a Microsoft account that doesn’t exist in the Azure AD tenant you’re targeting (“Microsoft Services”), so the portal won’t let you access the portal application (ID e6694c91-1590-4e35-9bb7-b865c638b9c1).

Here’s how to resolve it:

• Azure services use Microsoft Entra (Azure AD) for authentication. If your MSA (e.g., your personal Outlook/Live account) isn’t a member of the tenant you’re trying to access, you’ll hit that error.

• The portal application itself is multi-tenant, but your account must be known to the tenant (either as a native user or a guest).

What you can try

1. Switch to the correct directory – In the Azure portal, click on your profile icon (top-right) → “Switch directory.” – If your account is already invited to any other tenant, that directory will show up here. – Select it and try signing in again.
2. Ask the tenant admin to invite you as a guest user – Have a global administrator in “Microsoft Services” go to: Azure portal → Entra ID (formerly Azure AD) → Users → New guest user → Invite user – They can enter your Microsoft account email as an external (B2B) user. – Once the invite is redeemed, you’ll see that tenant in your “Switch directory” list and can access the portal.
3. Use a different (work/school) account – If you have a work or school account that already exists in that tenant, sign in with that instead of your personal MSA.

Hope this helps you get logged into the right tenant! Let me know if you have any more questions.
