By default, a user's Windows NT profile is created and maintained in the %SystemRoot%\Profiles\
username folder.
A user's Windows NT profile is made up of two components, folders and registry settings. The %SystemRoot%\Profiles\
username\Ntuser.dat file is started in the
HKEY_CURRENT_USER registry hive every time that a user logs on to a Windows NT computer.
The Exchange Administrator settings are maintained in the following registry keys:
HKEY_CURRENT_USER\Software\Microsoft\Exchange\MSExchangeAdmin
-and-
HKEY_CURRENT_USER\Software\Microsoft\Exchange\MSExchangeAdminCommon
