Hi, we have recently move from exchange 2003 sp2 to exchange 2010 sp2. All mailboxes and public folders as well as the address book have been moved to exch2010. Now i want to un-install exchange 2003 via the control panel. First thing i notice is that the Microsoft Exchange icon in Add Remove programs has a padlock sign. I have never seen this before. When i click on Change/ Remove on MS Exchange, its says 'setup is loading the installation components and that it may take a minute or two'. But nothing actually happens after 5-10 mins. Not sure where to go from here. thanks Mo
