Outlook “Suggested Contacts” doesn’t work with exchange

Hi


I have got outlook 2010 initially my work email was on POP3/IMAP (I was using IMAP) and outlook “Suggested Contacts” was working fine no problem ,,,,means when I try to type any address in “To” or “CC” fields automatically gets completed.


Then my company change email accounts for all personnel to from POP3/IMAP to Exchange, I set up a new profile on my outlook 2010 to receive email from the exchange, and IMAP is not working any more.


How can I make those “Suggested Contacts” that were working with IMAP before to work with Exchange email ?


Thanks
