tfs work items can not be modified after user is renamed in Active Directory


Staff member
TFS stores information about who created or who activated a work item and for some reason checks its validity whenever the work item is modified.

When a user is deleted from active directory or renamed in active directory, all work items even slightly has connection with the user can not be modified. Usually the error message is something like ...
TF20015: The field 'Activated By' contains the value 'blah blah blah' that is not in the list of supported values.

I've found a <a href="" rel="nofollow">blogpost</a> which recommends tweaking the TFS database, which is something not supported nor recommended by Microsoft.

What can be done to resolve this?
