Hello @MARCIO S
Thank you for posting your query on Q&A.
I understand that you are getting error 403 while accessing the Microsoft Entra ID for your student account.
This error (403) typically means the admin of the tenant has not given the permission to access the "Admin Portal" with a non-administrator account. which limits access to the Microsoft Entra admin center for non-admin users. This restriction can be found in the settings, where the global administrator has selected "Yes" to restrict access.
Refer to this article - https://learn.microsoft.com/en-us/azure/active-directory/fundamentals/users-default-permissions which talks about the kind of permissions a user has, and type of restrictions admin can apply within the Azure AD to restrict access.
Sometimes this issue occurs if there is something blocking the network connection. If this is the case, this issue can often be resolved by whitelisting the required endpoints as mentioned in our Microsoft documentation: https://learn.microsoft.com/en-us/azure/azure-portal/azure-portal-safelist-urls?tabs=public-cloud#azure-portal-framework
Please try updating the browser to the latest version and check using the Chrome browser instead of Edge to see if you get the same results.
To resolve this issue, there are two possible methods: 1.Reach out to your global administrator and ask them to assign any role to you. This will grant you access to the Microsoft Entra admin center, even if the restriction is set to "Yes". As long as you have any role or custom role assigned, you will not be restricted from accessing the portal.
2.The global administrator can disable the restriction by selecting "No". This will allow non-admin users, including service administrators like yourself, to access the Microsoft Entra admin center without any issues.
I hope this clarifies things. Please contact us if you have any additional questions.
