Not able to access the Azure Devops . Error 401

Hi @Apil Faterpenkar ,

Thanks for reaching out to Microsoft Q&A.

Refer https://learn.microsoft.com/en-us/azure/devops/organizations/accounts/resolve-orphaned-organization?view=azure-devops#when-your-azure-devops-administrator-isnt-a-member-of-the-target-organization to resolve 401 error.

Try below steps:

1. Sign in to your organization (https://dev.azure.com/{yourorganization}) using the credentials granted to the Azure DevOps Administrator role in Microsoft Entra ID. An error page appears where you can claim ownership.
2. Select Claim Ownership, provide a short justification, and then select Claim Ownership once again. A notification of the ownership transfer with your provided justification gets sent to all Azure DevOps Administrators in your Microsoft Entra ID. You will be redirected to the organization overview page.

If you are encountering a 401 error when trying to access Azure DevOps, it typically indicates that your identity does not have the necessary permissions to access the organization or a specific resource. Here are some common causes and solutions:

1. Identity Membership: Ensure that your identity is a member of the Azure DevOps organization. You may need to contact your Azure DevOps administrator to confirm your membership.
2. Sign-in Alias: Make sure you are signing in with your user principal name (UPN) and not an alias.
3. Read Permissions: Check if your identity has the required Read permissions for the project or resource you are trying to access.
4. B2B Guest Status: If you are a B2B guest in the Microsoft Entra tenant linked to the organization, ensure that you have accepted the invitation to the tenant.
5. Account Confusion: If you have both a personal Microsoft account and a Microsoft Entra account with matching email addresses, ensure you are signing in with the correct account.

If these steps do not resolve the issue, you may want to try signing out and signing back in, or using a private browsing session to eliminate any cached credentials that may be causing the problem.
