Q&A: Import IMAP Folders into Exchange Server 2007

My company had two email systems, Merak Mail running on one server (for hosted clients) and Exchange 2003 running on SBS 2003 for internal stuff. Our company decided to consolidate both resources into a single Exchange 2007 server. We migrated most of our small clients to our Exchange 2007 server but we are left with several clients who have mail in IMAP folders on the Merak system and no way to move it to Exchange 2007.

From my understanding, Exchange 2003 had an IMAP import wizard to take mail from any IMAP source and bring it into mailboxes. It is also my understanding that this feature was removed from Exchange 2007. Is there a way to import the mail from an IMAP source into Exchange 2007?
