Following comes from Senior Support Engineer Nitish Nagpal.
One of my customers was facing an issue with the TFS2010 Team Web Access in a collection that was ported over from another TFS 2010 install. They were not experiencing this issue with newly created projects on their server. While trying to edit a query in Team Web Access (TWA), they got the following error message: “Error HRESULT E_FAIL has been returned from a call to a COM component.”
This issue arises when:
1. They try to create a new work item – user story, bug, task etc.
2. They try to edit an existing query.
3. They try to open a work item from a query result set.
4. They search for a work item by the WI ID.
