When trying to open the Iteration Backlog.xlsm file in Team Explorer, I’m getting the following error:
“TFS80076: The data in the work item is not valid or you do not have permissions to modify the data. Please correct the problem and retry.”
No idea what I did wrong. The only thing I changed were the iterations. So I renamed the first iteration back from ‘Sprint 1’ to the original name ‘Iteration 1’. Afterwards the document opened fine.
Note: Afterwards I found this post on the MSDN forums. There someone mentions that the issue is solved if you also update the related queries after changing the iteration name.
