Log-in tenent / wrong organization

Question

Hello,

I have very weird situation with my accounts. I have two personal accounts <  [Removed PII]@gmail.com> and <  [Removed PII]@naver.com> and one organization <  [Removed PII]@fau.de>( I am not sure if this account is correct). Anyway, when I log-in https://ai.azure.com with the gmail account, the logged-in account is the <naver> account and the directory is FAU which is the organization. Why this happens? I want to decouple everything.

I removed all coockies and caches but still the same. I tried it with in a private mode in Edge, it was also the same.

.

Answer 1

This happens due to how Microsoft personal accounts (MSA) and Microsoft Entra ID tenants are linked, not because of cookies or browser cache.

At some point, one of your personal accounts (Gmail or Naver) was associated with the FAU Entra tenant (for example, added as a guest or used while accessing an Azure/AI service). When you sign in to https://ai.azure.com, Microsoft automatically resolves the sign‑in to the last linked tenant and identity, which is why:

• Gmail sign‑in resolves to the Naver account
• The directory defaults to FAU
• Clearing cookies or using InPrivate mode does not change the behavior

How to decouple it:

1. Sign in to https://myaccount.microsoft.com/organizations using each personal account.
2. Leave the FAU organization if it appears there.
3. If “Leave organization” is not available, contact FAU IT and ask them to remove your Gmail and Naver accounts from their Entra tenant (Users / Guests).
4. After removal, use https://login.microsoftonline.com/common?prompt=select_account to force account selection.

This behavior is by design when a personal account is linked to an Entra tenant; it is not a browser issue or a bug.

Hey there, Jinho Kim

When you sign into your Gmail account, it looks as though your Gmail account belongs to a tenant. When you sign into Azure and sign up for the subscription (free trial or pay as you go), it will create a tenant for you.

Please can you sign into the Azure portal here: https://portal.azure.com/#settings/directory

When you have signed into your account, you will see all of the tenants you are apart of

If you are signed into the wrong tenant, please use the 'Switch' option to switch to the tenant you need to be apart of.

If you are wanting to leave the tenant, you can ask the administrator of the tenant to remove your account. They just need to sign into their account on the EntraID service here: https://portal.azure.com/#blade/Microsoft_AAD_IAM/ActiveDirectoryMenuBlade

They can then navigate to your account by clicking onto 'Users' found under 'Manage'. Alternatively, you can leave the tenant by signing into here: https://portal.azure.com/#view/Microsoft_AAD_IAM/DirectorySwitchBlade/subtitle/

Then select the tenant you wish to leave, and click leave.

Hope this helps,
Nathan

The behavior is caused by multiple Microsoft identities that share or conflict across personal and organizational accounts, and by the way Microsoft sign-in chooses an account and tenant for a given email.

Key points from the described scenario:

• There are two personal Microsoft accounts (based on @gmail.com and @naver.com).
• There is also an organizational account in the FAU tenant (@fau.de).
• When signing in with the Gmail address, the session ends up as the Naver-based account in the FAU directory.

This typically happens when:

1. The same email address or user principal name exists both as a personal Microsoft account and as a work/school (organization) account, or
2. A personal account has been invited as a guest into an organization’s Microsoft Entra (Azure AD) tenant, and the sign-in flow automatically routes to that tenant, or
3. The email or user principal name used to sign in does not match the user/account expected in the Microsoft service, so the platform maps the sign-in to a different existing identity.

Relevant behaviors from the documentation:

• It is possible to have two accounts with Microsoft using the same email address: a personal account and a work or school account. In such cases, Microsoft may prompt “Which account do you want to use?” and route sign-in based on that choice. Which account do you want to use?
• Personal accounts can also be guest accounts in an organization’s Microsoft Entra tenant. These appear as guest users and are used to collaborate in services like Teams, OneDrive, or SharePoint. What's the difference between a Microsoft account and a work or school account?
• If the email/UPN used to sign in does not match the user/account expected by the service, the Microsoft Identity Platform may map to a different account that already exists for that email/UPN. Customer Support Portal - Troubleshoot Microsoft Identity Platform login

To “decouple” and regain control, use these supported approaches:

1. Check which organizations each work/school account is associated with
   • Sign in with the FAU work/school account at the My Account portal.
   • Go to Organizations.
   • Review the Home organization (FAU) and any Other organizations. This shows where that work/school identity is used. Manage organizations for a work or school account in the My Account portal
2. Check whether personal accounts are guests in FAU or other tenants
   • Still in the Organizations page (when signed in with the work/school account), verify if the Gmail or Naver addresses appear as guest accounts in any tenant.
   • If a personal account has been invited as a guest and that causes confusion, an administrator can remove or adjust that guest entry. Personal guest accounts cannot be renamed or have their passwords reset by the tenant; they are controlled by the personal Microsoft account owner. What's the difference between a Microsoft account and a work or school account?
3. Rename or alias the personal Microsoft account if there is a collision
   • If a personal Microsoft account and a work/school account share the same email address, Microsoft may repeatedly route sign-in to the wrong one.
   • To avoid this, rename the personal Microsoft account by changing its primary alias or adding a new alias and making that primary. This separates the identity used for personal services from the one used for the organization.
   • This is done in the Manage how you sign in section of the Microsoft account, then selecting Make primary for a new or existing alias. Which account do you want to use?
4. Ensure the correct account is selected when signing in
   • When prompted with multiple accounts that look similar (for example, same email but one personal and one work), explicitly choose the correct one.
   • If a Microsoft service signs in but does not show expected capabilities, it may be using the wrong identity; in that case, sign out and sign back in, selecting the correct work or personal account. Troubleshoot sign-in issues and account access problems
5. If the wrong tenant is reached in a web app
   • For services like Viva Engage, the guidance is to:
     • Close all browser windows and retry, or
     • Use separate browsers or in-private/incognito windows for different tenants.
   • If sign-in still routes to the wrong tenant or to an unexpected account, tenant admin intervention is required to correct configuration issues. When I log in to Viva Engage I get the wrong tenant

If the FAU tenant is not intended to be associated with one of the personal accounts, the FAU administrator can:

• Remove that personal account as a guest from the FAU tenant, or
• Adjust any configuration that automatically associates that email/UPN with FAU.

If there is a same-email collision between a personal and work/school account, renaming the personal account’s primary alias is the supported way to fully decouple them.
