eM Client and MailEnable Server - several problems

I have 2 accounts on a MailEnable server with Exchange option. When I add these accounts using “Exhange” in eM, mail is added, but not the calendar, notes and contact service. When I add the account as Outlook.com accounts, I do get mail (imap/smtp) and the calendar/notes/contacts service!

The main problem now is that sent email does not appear in any sent-items folder. THese folders sync perfectly any previous sent items, but the new mail items disappear. The mail is sent, arrives at its destination, but disappears from the account.

How can I solve this issue of missing all mail in sent items, and is there a better way to get Mail & Calendar from an Exchange Account (by MailEnable)?
