[visual-studio-2012] How can I change the default credentials used to connect to Visual Studio Online (TFSPreview) when loading Visual Studio up?

When I load Visual Studio 2012 up, it will attempt to connect to the previous TFS server that it was connected to.

On one of my machines (that also happens to connect to occasionally TFS2008 and TFS2010 servers) always seems to default to completely the wrong account for connecting to Visual Studio Online (tfspreview), and if I were to try and get the latest version, it'll give an error of the form:

Microsoft Visual Studio

Source Control Explorer

TF204017: The operation cannot be completed because the user (Account Service ([my tfs server]) does not have one or more required permissions (Use) for workspace [my workspace];[my live id].

OK

How can I influence Visual Studio 2012 to default to the correct credentials, rather than a seemingly fictional Account Service one?

After failing with cleaning the Credentials from the Manager and clearing the VS cache, consider to repair Visual Studio from the Visual Studio Installer (VS2017). I personally found no other solution working.

For Windows 8:

Control Panel -> (Search for) Credentials Manager -> Check Web Credentials

this worked for me...

You need to remove TFS credentials from Windows Vault to clear and force to ask new TFS credentials in Visual Studio

1. Go to Control Panel (Start -> Control Panel).

2. Click User Accounts ( or User Accounts and Family Safety->User Accounts in Windows 7 Machine)

3. Click Credential Manager (or Manage your credentials)

4. In Credential Manager page, you can see the two type of credentials

      i. Windows Credentials
      ii. Generic Credentials
   

5.Click on two credentials modify link, click the link Remove from vault to remove stored TFS credentials.

Now, When you login into Visual Studio you will be asked to give credentials to connect TFS.

Note: Don't forgot to uncheck the option Remember my credentials to force to ask credentials for every TFS connections.

I tried opening my Credential Manager but could not find any credentials in there that has any relation to my TFS account.

So what I did instead I logout of my hotmail account in Internet Explorer and then clear all my Internet Explorer cookies and stored password as detailed in this blog: Changing TFS credentials in Visual Studio 2012

After clearing out the cookies and password, restart IE and then relogin to your hotmail (or windows live account).

Then start Visual Studio and try to reconnect to TFS, you should be prompted for a credential now.

Note: A reader said that you do not have to clear out all IE cookies, just these 3 cookies, but I didn't test this.

cookie:@login.live.com/
cookie:@visualstudio.com/
cookie:@tfs.app.visualstudio.com/

I ran into this same issue. Someone had logged onto my computer and used their TFS credentials. I'm running VS2012, Windows 7, and the network admins have Credential Manager disabled.

Run this command from a command window with the same user your running visual studio as.

rundll32.exe keymgr.dll,KRShowKeyMgr

You'll see a popup with all your stored credentials. Remove the one for your TFS server.

Note: You will need to restart visual studio because it caches the tfs credentials.

i found another solution:

1. start session in TEAM
2. go to SOURCE CONTROL and select WORKSPACE (mark in red)
3. then Add new Workspace... why?
4. because you dont work in the same workspace whey you change your account in TFS (i dont know why)
5. and ready to MAP your project again.

Its 100% guaranteed to work.

You can also try to reset visual studio setting

1. Open Visual Studio Command Prompt

2. Enter command Devenv /ResetSettings

It will remove already saved TFS account and ask for credentials
