Hi @Lars Liden,
The screenshot shows that the current sign-in page accepts only a work or school account. This does not necessarily mean the Gmail-based Microsoft account has been converted into an enterprise account. The browser may be using the wrong Microsoft identity, tenant, or cached sign-in session.
To better understand the issue, could you please confirm:
- Can the same Gmail address sign in successfully at account.microsoft.com?
- Does the error also occur in an InPrivate/Incognito window?
- When you enter the Gmail address, are you prompted to choose between a Personal account and a Work or school account?
- Has this Gmail address previously been invited as a guest to a Microsoft Entra organization?
- Were you previously able to access the Azure subscription using this same account?
These details will help determine whether the issue is related to a cached sign-in session, the selected account identity, or the Microsoft Entra directory associated with the Azure subscription.
Please try the following
- Open an InPrivate/Incognito browser window and go directly to Azure portal.
- Enter the Gmail address and, if prompted to choose an account type, select Personal account.
- If the wrong identity is selected automatically, clear Microsoft cookies or try another browser. Microsoft specifically recommends private browsing or clearing cookies when Azure automatically signs in as another user.
- Confirm that the Gmail address can still sign in successfully at Microsoft account. This verifies that the address is recognized as a personal Microsoft account. Microsoft distinguishes personal accounts from organization-managed work or school accounts.
If the error appears immediately even in a private window, please check whether the address was previously invited as a guest to another organization. A personal Microsoft account can also exist as a guest account in a Microsoft Entra organization, but the personal identity and guest identity remain separate.
Thank you again for your time and understanding. I really appreciate your patience, and I’m here to help. Looking forward to your response.
