Error TF30063: You are not authorized to access … \DefaultCollection
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 MyProjectDefaultCollection.
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.
Try to follow the below steps, this might help:
First, click on the "Connect to Team Projects button" (As shown in the screenshot)
Then, right-click on the project you are getting issues with and connect it by clicking Connect
If you are getting error:
Tf30063 You are not authorized to access TFS
So, for this you can clear the TFS cache and reconnect the TFS. You can clear TFS's cache from following location, just change the user name as per your system. Once cache will delete, probably TFS will ask for credential to reconnect. You need to provide valid credentials and TFS will work.
