I went through a painful Exchange 2007 to Exchange 2010 migration and faced a new problem - the utility I used for Active Directory management does not support Exchange 2010. Please advice a piece of software that could help (I run network for less than 1000 users).
Features I need to be included:
Establish, remove mailboxes, remove Exchange-specific properties from AD objects, provision mailboxes. (web interface would be a plus)
