1) I have a system of Microsoft Exchange 2003
2) I just created a server for Exchange 2007 (with the same Organization and Domain)
3) When I open the Exchange 2007 using EMC (Exchange Management Console); there are the followings:
-All the mailbox from the Exchange 2003 are called "Legacy Mailbox"
-All the new mailboxes that i just created using EMC; are called "User Mailbox"
4) I want to migrate all the mailboxes from Exchange 2003 to Exchange 2007
5) My question:
First: What should i do with this "Legacy Mailbox"? Should i convert it "User mailbox"? If Yes, How to do it?
