I have a problem with adding of new accounts into Team Foundation Server 2010. I can add a new domain account into group Contributors of my team project without problems but after that I can't see it in the list of available accounts, for example, in the
drop down list 'Assigned To' at a work item page.
The added user can see the project, do check-in and check-out but he can't get access to the project work items. He has got an error
TF201072: A user or group could not be found. Verify that the users and groups used in your work item type definition have been added to Team Foundation Server.
Can anybody help me?
