Our domain includes a lot of users who have account names with spaces, e.g. 'Fred Bloggs'.
We need to change this format so that is complies with standards which exclude the use of spaces.
When we change the user account name, will this create a brand new profile on the computer and as such all program configurations will need to be re-configured? I'm also thinking that it would break ActiveSync and roaming profiles would also need to be updated?
