NEEDED ADVANCED IMAP SETTING TO SET UP EMAIL IN NOKIA LUMIA 620?

I have NOKIA Lumia 620 mobile.(Windows 8 mobile with Amber update)
I send emails from this mobile.
My webmail client is Open-Xchange.
I can receive & send emails from mobile.
Moreover when I send Emails from the mobile they are not
listed under SENT MAILS (Sent Items) when i view them from my PC.
I have entered the following Settings.

Under mail settings
incoming email server: imap.abc.com:143
outgoing SMTP email server: smtp.abc.com:25
I have CHECKED: outgoing server requires authentication
I have CHECKED: use the same username password for sending mail
UNDER ADVANCED SETTINGS
I have UNCHECKED: require SSL for incoming email
I have UNCHECKED: require SSL for outgoing email

THERE's NO SUCH SETTINGS LIKE
IMAP path Prefix: Inbox

There's no configuration setting to change the 'Mailbox Behaviors'
(under advanced settings) of the sent mailbox so that it saves the
sent message on the server, instead of the Nokia Lumia 620.

There's no problem in iPhone as it has the needed settings.

There's no problem with Yahoo Mail & Gmail.

IS THERE ANY SOLUTION?

Its very important.
