TF31003: Your user account does not have permission to connect to the Team Foundation Server {0}

VSTS | TFS 2018 | TFS 2017 | TFS 2015

You might receive this error when you try to connect to VSTS (VSTS) or an on-premises Team Foundation Server (TFS).

Problem Resolution
You can't switch between different organizational accounts. If you work with several VSTS accounts that connect to different directories, such as accounts that are created from the Microsoft Azure Preview Portal, the sign-out function might not work as expected. For example, you can't switch between different organizational accounts to connect to multiple accounts that are linked to directory tenants.

When this problem occurs, you see a flashing blank sign in dialog box several times. Then, you receive either TF31002 or TF31003 error after you connect to or add a new connection in "Connect to Team Foundation Server" dialog box.

To resolve this problem, apply the most recent Visual Studio update.

You have multiple Microsoft accounts that you use to connect to VSTS. You may have used another account for one purpose and it was cached. To run Visual Studio under an account that is different from your logged on Windows account, open the context menu for devenv.exe to access your run as options.

Context menu for Visual Studio devenv.exe



The executable is in this folder: Drive:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE\.

Your password in Active Directory or Azure Active Directory has expired. Verify that your password is active.

If you didn't log off after your password expired, you might still be able to use your account on your machine, but not authenticate with other systems. Try changing your password.

Or, if you recently changed your password, but still have some service using your old credentials, it might be causing your account to lock for some period of time. Try logging off your client computer and logging back on.
Your user account doesn't have sufficient permissions to connect. Check with your VSTS account administrator or TFS administrator or that you have the necessary permissions to connect. For VSTS, you must have an active, valid license. See Assign licenses to users of VSTS for details.
