please help me

IMAP(S) and POP3(S) - of wich you should only ever use their SSL-variants IMAPS(993) and POPS(995) are client ports and thus need to be forwared to your Exchange Server, not your eFa.

What budy says.

Only map your smtp traffic ports to EFA. Map the imap/pop ports to your exchange server - and you shouldn't use pop if you can avoid it.

why i should use pop?
i use pop3 and imap for outlook connection.

…because you said so in your opening post… I don't even know, if Exchange supports pop at all…
Just use IMAP/SSL on port 993…

budy, he was answering my question.

The problem with pop is that it is an old protocol designed for when mailboxes were small and only consisted of an inbox.

If the outlook clients are going to access the exchange server, and they are not going to use the Outlook Web Access connector, then imap is the best choice.

I always thought, that pure pop servers have died looong ago.

Nope. Still with us. Still with us...
