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

Solution 1:

When I came accross this issue none of the provided answers solved this problem or if it did I didn't like recreating the project. The way I ended up solving the issue:

1. Clicking on the "Connect to Team Projects button" (The plug next to the home button in the Team Explorer tab)
2. Right click the project you are getting this issue on.
3. Click Connect.

I guess the "Remember me" cookie timed out but gave me a generic response for trying to push or pull any code.

Solution 2:

I solved this issue by using the browser from within Visual Studio, View->Other Windows->Web Browser; Ctrl+Alt+R (or * Ctrl+W, W* in VS versions before VS2010) to navigate to the TFS page and log out of the wrong account and log back in.

For me, the issue was caused by using another live-id to unlock a windows phone for development. Somehow the credentials got cached, it seems.
