Team Foundation Server: Multiple Identities Found

Question

Up until yesterday, my connection to Team Foundation Service was working perfectly.

A separate requirement caused me yesterday to rename my computer. After that, there were some errors about the workspace which I was able to fix with the TF command, but I can't find anything about this new error, which arose after I renamed the workspace:

Please note that the blacked-out email addresses are all three identical.

I have no idea how to "specify one of the following workspace specs" from a MessageBox! Any ideas?

TFS for years has been among the worst user experiences I've ever seen.

Answer 1

For me it helped to just sign out from TFS via the "Configure Team Projects" window, and then log in again.
