Hi There!
We have a SharePoint 2010 site with 40 users.
All users account name is "Server\Username" i.e. DS6160\davism
We have changed the user display name by using the Set-SPUser command i.e. changing DS6160\davism to become Mark Davis.
We have started noticing that after a while all the users display names are reverting back to DS6160\davism instead of mark Davis!
Does anyone know what causes this?
