Error TF30063: You are not authorized to access …

Question

I'm using TFS Preview (Team Foundation Service) with one of my projects with Visual Studio 2012. I'm also using an on-premises TFS server with most of my projects. When I use my on-premises TFS after using TFS preview and go back to using TFS preview, I get this error:

TF30063: You are not authorized to access MyProject\DefaultCollection.

If I go to Team → Disconnect TFS and then connect to TFS preview again, I'm able to see a "Loading identifiers" loading screen coming up, but in the end I don't get to enter my credentials to TFS preview (my Microsoft account) and as a result, the TF30063 error still occurs.

I suspect this has something to do with my Microsoft account (i.e. Live ID). I'm logged in to Windows with the same Microsoft account that I use at TFS preview. I have logged in to other sites (Windows Development Center, MSDN, etc.) with other Microsoft accounts, but I verified that if I log out of these services and re-login with the correct Microsoft account, I still get the TF30063 error when I try to log in to TFS preview from Visual Studio.

Answer 1

In team explorer I removed project... then in Manage Connections, clicked on 'Connect to a Project...'

In this screen choose your project then click on Connect... this solved my problem.

Answer 2

I have upgraded TFS 2015 to TFS 2017, and then the TF30063 error occured on one of my client machines. None of the solutions here worked...

For me the only solution that worked was running the following command from the Developer Command Prompt:

tf workspaces /collection:https://tfs.xxxxx.com/tfs/DefaultCollection

Of course, you need to adjust the url to the valid one.

Answer 3

For me the error came after changing my password for my AD account.

I had to remove the line from credential manager (which contained the previous password.)

Then it worked again.
