I have a setup of Exchange 2003 with Outlook 2003 and Outlook Web access as
clients. We have around 2500 clients, which is setup through Active directory.

I need to change the “user logon name� found under “Account� tab in the
properties of each user to all small characters (at present first letter of
firstname and lastname are capital).

Is there a tool which can be used to achive this without having to change
each user’s properties manually??
