IMAP has the advantage over POP3 that it doesn't actually download messages
from the Exchange Server, it actually reads the messages from the
Information Store, like standard Exchange client. It acutally works as
Once you connect to the Exchange Server using IMAP your client synchronizes
your local message store with the Exchange Server and downloads all message
When you open a message it is actually downloaded to your client, but NOT
removed from the Exchange Server, just downloads for opening attachments and
IMAP client thus works as a mirror of your Exchange Server mailbox
As for Windows Address Book and LDAP, you do NOT download/import an address
list, you search the Exchange GAL on-line via the LDAP protocol. From WAB
select tools, accounts and add your Exchange Server in the list. Choose to
check names against the server when asked.
All protocols (IMAP, POP and LDAP) are enabled/disabled under
